UV tunable biobased pressure sensitive adhesives containing piperonyl methacrylate
Novel waterborne pressure sensitive adhesives (PSA) with biobased contents up to 71%, and UV-light tunable features have been developed using piperonyl methacrylate as hard monomer. The biobased monomer was synthesized from piperonyl alcohol (derived from black pepper) and its homopolymer was fully...

| Resumo: | Novel waterborne pressure sensitive adhesives (PSA) with biobased contents up to 71%, and UV-light tunable features have been developed using piperonyl methacrylate as hard monomer. The biobased monomer was synthesized from piperonyl alcohol (derived from black pepper) and its homopolymer was fully characterized. Emulsion polymerization was chosen as sustainable strategy to copolymerize piperonyl methacrylate together with biobased 2-octyl acrylate to produce high solids content latexes for pressure sensitive adhesives applications. The UV-light curing ability of the piperonyl methacrylate moieties in the copolymer backbone yield PSAs with excellent shear resistance and reasonable adhesive properties (tack and peel). |
