“…Higher M w was obtained for P4 derivatives compared to P5 and P6 derivatives (compare Table ), which is desirable according to further PSA application. The latter reached molecular weights of about 300 kDa ( M w ), which is at the lower end of typical PSA formulations . Additionally, P4 polymers showed a high dispersity ( Đ ), probably due to the formation of short‐ and long‐chain branches through intra‐ and intermolecular chain transfer to polymer.…”

This work investigates the synthesis of bio‐based pressure‐sensitive adhesives and their characterization in terms of mechanical properties relevant to processing and application. The synthesis of monomers based on various fatty acids derived from vegetable oils as renewable feedstock via a one‐step, a two‐step, and a three‐step route is described. The resulting monomers are polymerized via free radical polymerization resulting in high molecular weight polymers with adhesive properties. Adhesives are also obtained as aqueous dispersions by means of miniemulsion polymerization. In particular, the monomer acrylated methyl oleate (4ac) and the thereof derived polymer are intensively studied. The synthesized homopolymers show characteristic mechanical and adhesive properties similar to conventional pressure sensitive adhesives.

“…Furthermore, owing to their hydrophobicity and biocompatibility PIBs are frequently applied as building blocks for the synthesis of amphiphilic block copolymers and amphiphilic micelles/vesicles . The PIBs with low molecular weight are also important and widely used as tackifier in the pressure‐sensitive adhesives for tapes and removable labels . Mass spectrometric methods can provide essential information on the molecular mass, the mass of the repeating unit and the end‐groups of polymers.…”

Low molecular weight polyisobutylenes (PIB) with chlorine, olefin and succinic acid end-groups were studied using direct analysis in real time mass spectrometry (DART-MS). To facilitate the adduct ion formation under DART conditions, NH Cl as an auxiliary reagent was deposited onto the PIB surface. It was found that chlorinated adduct ions of olefin and chlorine telechelic PIBs, i.e. [M + Cl] up to m/z 1100, and the deprotonated polyisobutylene succinic acid [MH] were formed as observed in the negative ion mode. In the positive ion mode formation of [M + NH ] , adduct ions were detected. In the tandem mass (MS/MS) spectra of [M + Cl] , product ions were absent, suggesting a simple dissociation of the precursor [M + Cl] into a Cl ion and a neutral M without fragmentation of the PIB backbones. However, structurally important product ions were produced from the corresponding [M + NH ] ions, allowing us to obtain valuable information on the arm-length distributions of the PIBs containing aromatic initiator moiety. In addition, a model was developed to interpret the oligomer distributions and the number average molecular weights observed in DART-MS for PIBs and other polymers of low molecular weight.

“…The final goal of our research is an innovative molecular design method for rational development of new pressure‐sensitive adhesives (PSA) with tailored performance properties, which can be produced by blending of nonadhesive hydrophilic functional polymers. The PSA are viscoelastic polymer materials capable of forming strong adhesive bonds with substrates of various chemical nature under application of a slight pressure (1–10 Pa) over a short contact period (1–2 s) 21…”

Correlations have been established between mechanisms of molecular interaction, the energy of intermolecular bonds, nanoscopic free volume, phase state, and such macroscopic physical properties as linear and large‐strain viscoelasticity, relaxation, water‐absorbing capacity, and adhesive joint strength of pressure sensitive adhesives based on nonstoichiometric polyelectrolyte complexes. The polyelectrolyte complexes are formed by mixing of a polybase, copolymer of N,N‐dimethylaminoethyl methacrylate with methyl methacrylate and butyl methacrylate (PDMAEMA‐co‐MMA/BMA), with a polyacid, copolymer of methacrylic acid and ethyl acrylate (PMAA‐co‐EA) in the presence of triethyl citrate (TEC) as a plasticizer. Rubber‐like elasticity and pressure sensitive adhesion of the polyelectrolyte complexes on the macroscopic level have been demonstrated to be the result of specific coupling of such generally conflicting properties of polymer materials as sufficiently strong intermolecular cohesion energy with comparatively large free volume (vacant space between neighboring macromolecules) at the nanoscopic scale. © 2011 Wiley Periodicals, Inc.
