Abstract

Elastomers based on acrylates, which are comprised, in the amount of at least 40 wt. % and as much as 100 wt. %, of one or more copolymers having a molecular weight >50,000 daltons and comprised of units of: PA0 i) acrylate monomers in the amount of 50-95 wt. %, and PA0 ii) macromonomers comprised of a vinylic group and, covalently bonded with such group, a polyvinyl unit selected from the group of acrylates and methacrylates and having a glass transition temperature Tg at least 60.degree. C. and molecular weight 500-100,000 dalton.
