“…The anthraquinone dyes, being famous for their beautiful color brilliance and prominent fastness, have been widely used in dyestuff and colorant industry. A series of polymerizable dyes containing anthraquinone chromophore have been synthesized and used to fabricate the covalently colored polymer latex in our previous research, 21,22 but the color strength of these synthetic dyes are still not very satisfactory. Since the molar absorptivity of the dye is determined by the electron donating substituent of the anthraquinone structure, it is believed that the introduction of amino group on AQ will cause both bathochromic effect and hyperchromic effect.…”

“…18,19 In our previous work, the polymerizable azo and anthraquinone dyes were synthesized and utilized to prepare the red and yellow covalently colored latexes by different emulsion polymerization processes, and the storage stability of the latexes and the light fastness of the latex films were proved to be much better than that of the noncovalently colored latex. [20][21][22] For the further application, a kind of blue covalently colored latex with higher color strength was expected to complete the color species.…”

1‐(6‐acrylamidohexylamino)‐4‐(methylamino)anthraquinone (AHMAQ), a blue polymerizable dye, was first synthesized from an anthraquinone derivative, and its chemical structure was confirmed by 1H‐NMR and IR. Then, a series of covalently colored polymer latexes were prepared by semi‐continuous emulsion copolymerization of styrene (St), butyl acrylate (BA), and AHMAQ using 4,4′‐azobis(4‐cyanovaleric acid) (ACVA) as initiator, and the influences of AHMAQ and ACVA on the emulsion polymerization as well as the properties of the resulted copolymer latexes were investigated. Results showed that both the conversion of the dye monomer and the molecular weight of the latex polymer decreased with the increase of AHMAQ amount from 0 to 0.3 wt %. Increasing the ACVA amount resulted in higher monomer conversion but larger gel ratio, and optimum amount of ACVA was 1.2 wt % to the total monomers. Comparing with the noncovalently blue latex film colored with the unreactive dye, the light fastness of the blue P(St‐BA‐MAA‐AHMAQ) latex films was greatly promoted by the covalent incorporation of chromophores with polymer matrix. © 2012 Wiley Periodicals, Inc.

“…Due to the high binding capability of such vitamin, it provided a useful recognition molecule for tumour-targeted drug delivery. [21] The folic acid binds to the folate receptors on the tumour cells by active targeting, which leads to receptor-mediated endocytosis and controlled release of drug delivered to the cancer cells. [22] The hydrazone linkage is sensitive to low pH and hence the attached DOx in the nanocarrier is cleaved easily by the highly acidic environment in the tumour cells resulting in controlled release.…”

This development of MRI-visual order-disorder structures for cancer nanomedicine explores pH-trigger mechanism for theragnosis of tumour hallmark functions. Superparamagnetic iron oxide nanoparticles (SPIONs) stabilised with amphiphilic poly(styrene)-b-poly(acrylic acid)-doxorubicin with folic acid (FA) surfacing is employed as a multi-functional approach to specifically target, diagnose and deliver drugs via a single nanoscopic platform for cancer therapy. The functional aspects of the micellar nanocomposite is investigated in vitro using human breast SkBr3 and colon cancer HCT116 cell lines for the delivery, release, localisation and anticancer activity of the drug. Our work shows, for the first time, concentration dependent T 2 -weighted MRI contrast for a monolayer of clustered cancer cells. The pH tunable order-disorder transition of the core-shell structure induces the relative changes in MRI contrast. The outcomes elucidate the potential of this material for smart cancer theranostics by delivering non-invasive real-time diagnosis, targeted therapy and monitoring the course and response of the action before, during and after the treatment regimen.Submitted to 3

“…In contrast, cotelomerization of acrylic monomers is rarely investigated (cotelomerization of acrylic acid and n -octyl acrylate, 2-ethylhexyl acrylate or 2-phenylethyl acrylate in presence of 2-aminoethanethiol hydrochloride [ 33 ] and cotelomerization of methyl methacrylate and maleic anhydride with dodecyl mercaptan [ 34 ]). In the last decade, the works about telomerization have been directed towards receiving the amphiphilic polymers [ 35 ] or block copolymers [ 36 ]. The latest scientific reports (2020) concern the preparation of fluorosurfactants [ 37 ], preparation of hydrophobic coatings [ 38 ] and pioneering studies on telomerization of chitosan and hemicellulose with butadiene in water [ 39 ].…”

Influence of Acrylic Acid on Kinetics of UV-Induced Cotelomerization Process and Properties of Obtained Pressure-Sensitive Adhesives

et al. 2020

A new environmentally friendly method of photoreactive pressure-sensitive adhesives (PSAs) preparation was demonstrated. PSAs based on n-butyl acrylate (BA), acrylic acid (AA) and 4-acryloyloxy benxophenone (ABP) were prepared via the UV-induced cotelomerization process in the presence of a radical photoinitiator (acylphosphine oxide) and telogen (tetrabromomethane). Hydroxyterminated polybutadiene was used as a crosslinking agent. Influence of AA concentration (0–10 wt %) on kinetics of the cotelomerization process was investigated using a photodifferential scanning calorimetry method, selected physicochemical features of obtained photoreactive BA/AA/ABP cotelomers (molecular masses, polydispersity, monomers conversion and dynamic viscosity) and self-adhesive properties of obtained PSAs (adhesion, tack and cohesion) were studied, as well. It turned out that AA content is the important factor that influences monomers conversion (thereby the volatile parts content in prepolymer) and PSAs’ properties. As the acrylic acid content increases, the reaction rate increases, but the total monomers conversion and the solid content of the prepolymer decreases. Additionally, the adhesion and cohesion of PSAs were grown up, and their tackiness decreased. However, the AA content has no effect on molecular weights (Mw and Mn) and polydispersity (c.a. 1.5) of photoreactive cotelomers. The optimal AA content necessary to obtain a prepolymer with low volatile parts content and good PSA properties was determined.
