Three different acrylate monomers containing butyl acrylate, 2‐hydroxyethyl acrylate, and acrylic acid were designed to synthesize polyacrylate pressure‐sensitive adhesives (PSAs) by bulk polymerization process initiated via radical photo‐initiators under UV irradiation and UV‐thermal dual curing. Thermal crosslinker, KL‐1202, with trifunctional isocyanate groups was introduced into the prepolymer to form an intermolecular crosslinking network structure. An emphasis was placed on the effect of the KL‐1202 content on the microstructure and adhesive properties of PSAs. The viscosity and composition of prepolymer synthesized by UV initiation were tested by a rotational viscometer and Fourier transform infrared spectroscopy, respectively. The degree of crosslinking of the final PSA was evaluated by the gel content value obtained via Soxhlet extraction, while the molecular weights of the soluble parts of PSA polymers were measured by gel permeation chromatography. Dynamic mechanical analysis was used to characterize the viscoelastic performance of PSAs. Moreover, the adhesive properties of PSAs were determined through a series of tests including loop tack force, peel force, and shear resistance. It was found that the C=C double bond and the isocyanate group disappeared after UV radiation and thermal curing process. Dual‐cure acrylate PSAs compensate for limitations in UV‐induced cure of thick coatings. The Tg value, storage modulus (G′), and shear resistance of PSAs were improved while the loop tack force and peel force of PSAs decreased as the KL‐1202 content increased.

“…Therefore, the nal PSA structure contained 45 wt% from the self-crosslinked content of the monomers added (when HDDA content was 0%), which resulted from the hydrogen abstraction and chain transfer reactions of a number of tertiary carbon atoms of reactive monomers, such as butyl acrylate (BA), 2-hydroxyethyl acrylate (HEA), and acrylic acid (AA). 24,[27][28][29][30] Other PSAs were composed of 55 wt% to 80 wt% crosslinked contents when the HDDA crosslinker content increased from 0.1 wt% to 0.9 wt%. The remainders were soluble acrylate copolymers.…”

“…Similar reaction was occurred among AG and MAA as in the formation of AG microgel, except that MAA was introduced into the reaction after the generation of AG radical. The AG radical abstracted proton from the ethylene group of methacrylic acid leading to propagation of the polymer chains [23][24][25] through graft polymerization to form the Arabic gum-grafted-poly(methacrylic acid). Then, the cross-linking agent (MBA) was added into the emulsion system to terminate the chain propagation.…”

Carbohydrate polymers microgels are non-toxic and biocompatible which can be readily used in applications such as drug delivery, medicine, and pharmacy. This work synthesized Arabic gum (AG) microgel and methacrylic acid modified Arabic gum microgel (AGMAA) via water in oil emulsion polymerization technique using Tween 20 as surfactant and hexane as the solvent. The microgels were characterized using various physicochemical analysis such as Fourier Transform Infrared spectroscopy, thermal stability using Differential Scanning Calorimetry, diffraction pattern analysis using X-Ray Diffraction, morphology observation using Field Emission Scanning Electron Microscope and zetasizer was used to analyze the size and zeta potential. The rate of deformation was higher in AG microgel compared to the AGMAA microgel. The particle size and zeta potential of AGMAA microgel were found larger and more negative than AG microgel, respectively. The microgels particle size and zeta potentials were found dependent on the amount of methacrylic acid as the modifying agents. The microgels were encapsulated with doxorubicin through the swelling method and the in-vitro release was studied in medium with pH 4.2 and 7.4. The results suggest the potentials of these microgels for drugs delivery.
