Thermoplastically processible elastomers based on acrylates, which contain 40-100 wt. % of one or more comb polymers having a molecular weight greater than 50,000 Dalton, comprised of: n (A) 5-50 wt. % of macromonomers comprised of methyl methacrylate or copolymers of methyl methacrylate with comonomers chosen from other (meth)acrylic acid esters and styrenes; n containing a terminal unit with a radically polymerizable group and having a glass transition temperature (Tg) of at least 60° C., a molecular weight in the range 500-100,000 Dalton, and an index of refraction in the range n D =1.48-1.50; n (B) 5-90 wt. %, based on the total weight of the comb polymer, of monomers or monomer mixtures of formula I: ##STR1## where R 1 is a C 1 -C 12 -alkyl group; and (C) 5-50 wt. % based on the total weight of the comb polymer, of a phenyl group-containing radically polymerizable monomer. |
