Pressure sensitive adhesive

摘要

Pressure-sensitive adhesive material (I) based on acrylate copolymers also contains 2-15 wt% polymethyl methacrylate (PMMA) spheres with a particle size of 2-10 microns. Pressure-sensitive adhesive material (I) comprising (a) 85-98 wt% of a copolymer of (a1) 70-99 wt% (meth)acrylate of formula CH 2=C(R 1)-COOR 2, in which R 1H or methyl; R 22-20C alkyl and (a2) 1-30 wt% functionalised vinyl compounds, plus (b) 2-15 wt% PMMA spheres with a particle size of 2-10 microns. Independent claims are also included for (1) a method for the production of (I) by mixing components (a1), (a2) and (b) and then polymerising the mixture (2) a method for the production of (I) by polymerising the mixture of (a1) and (a2) and then adding (b) to the polymer .
