“…We used two types of polyacrylates; one was poly( n ‐butyl acrylate–acrylic acid) [P(BA–AA)], and the other was poly( n ‐butyl acrylate–glycidyl methacrylate) [P(BA–GMA)]. Both polymers are widely accepted as conventional PSA matrixes . The nanocomposites were prepared by the mixture of a polyacrylate‐type emulsion and ND aqueous dispersion.…”

A high performance and functional properties in pressure-sensitive adhesives (PSAs) are attractive in fundamental and industrial fields. To control the performance of PSAs, nanofillers have been loaded into them. In this study, we focused on composites of acrylic PSAs and nanodiamonds (NDs). The loaded NDs reinforced the mechanical properties and increased the performance of the PSAs. NDs in a PSA formed a network structure. In this study, we revealed that the acidic-basic state was a key factor in the control of the dispersion of the NDs. When a PSA emulsions and ND aqueous dispersion was mixed under basic conditions, the composites demonstrated higher PSA properties (tack, holding, and peeling strength). We investigated the effect of the ND loading on the PSA properties from the viewpoints of the nanostructure and acid-base interactions.

“…In particular, rosin is an effective adhesion promoter and viscosity controller. Therefore, it is expected that adhesive, stable, transparent, and thermally stable polymer films will be obtained when a rosin moiety is incorporated into the polymer structure . However, rosin is a multiple rigid‐cycle structure; it is often used in a chemically modified form by means of a Diels–Alder cycloaddition reaction to prepare difunctional or multifunctional monomers of polyesters with maleic anhydrine, acrylic acid and acrylates, Fullerene C60, amine, and so on.…”

A Diels-Alder adduct of rosin with tung oil was effectively prepared for use as a filler and adhesion promoter in UVcurable adhesives. The characteristics of the adduct were analyzed by Fourier transform infrared (FTIR) spectroscopy and ultravioletvisible (UV-vis) absorption spectra. The reaction mechanism was studied with gel permeation chromatography, thermogravimetric analysis, 1 H-NMR, and the density functional theoretical method. The FTIR and 1 H-NMR results showed that the Diels-Alder addition occurred between the rosin and tung oil. The still-existing characteristic peaks of the conjugated diene in the adduct, as shown in the FTIR and UV-vis absorption spectra, indicated that the most favorable reaction between the rosin and tung oil was when the rosin was used as the conjugated diene and the tung oil was used as the dienophile. The molecular weights of the adduct with different molar ratios showed that the most possible addition molar ratio between the rosin and tung oil was 3:1. The favorable addition mechanism was further proved by a comparison of the relative energies of different isomers of the adduct with theoretical calculation, and the most stable structure of adduct showed that the addition position of tung oil was the terminal C@C double bond. The properties analysis indicated that the adduct could improve the adhesion of UV-curable adhesives and reduce the curing shrinkage rate.

Rosin was reacted with hydroxyethyl methacrylate to produce a macromonomer. This macromonomer was used to partly replace styrene for the novel preparation of polymer microspheres with divinylbenzene via suspension polymerization. Orthogonal experiments were conducted to analyze the factors influencing the particle size, particle size distribution, swelling ratio and degree of crosslinking of the polymer microspheres. Fourier transform IR spectroscopy, thermogravimetry and scanning electron microscopy were used to examine the structures, thermal properties and morphologies, respectively, of the polymer microspheres. The results showed that the amount of dispersant had the greatest influence on particle size and distribution. On the other hand, the monomer ratio greatly influenced the swelling ratio and degree of crosslinking of the polymer microspheres. The decomposition temperature of the polymer microspheres increased upon introduction of the rosin moiety into the product. Open pores were abundant on the surface of the polymer microspheres due to the existence of the porogen, which provided a base for adsorption and separation. The present study opens a novel route for using naturally occurring rosin. Copyright © 2012 Society of Chemical Industry
