Abstract: UV curing non-solvent acrylic pressure-sensitive adhesives (PSA) were synthesized through bulk polymerization with 2-Ethylhexyl acrylate (2-EHA),Butyl Acrylate (BA),Methyl methacrylate (MMA) and Tetrahydrofurfuryl acrylate (THFA) used as acrylic monomers,acrylic acid (AA) and N,N-dimethylacrylamide (DMAA) used as functional monomers,4-acryloyloxy benzophenone (ABP) used as copolymerizable photoinitiators,2，2′-Azobisisobutyronitrile (AIBN) used as radical initiators and 1-dodecanethiol (NDM) used as chain transfer agent. The influences of functional monomers AA and DMAA, copolymerizable photoinitiators ABP and chain transfer NDM agent were discussed on performances of UV curing non-solvent acrylic pressure-sensitive adhesive (PSA). The other relative performances were then characterized. The results showed that when ω(DMAA)=10% and ω(AA)=2%,120℃ melt viscosity and the adhesive property of PSA were optimal; Copolymerizable photoinitiator ABP is suitable for the system of non-solvent acrylic PSA and PSA had the good UV-curing when mass fraction of ABP was 0.2%. The integrated properties of PSA are the best when mass fraction of NDM was 1.5%.
