MATERIAL FOR SAFETY-EFFECTIVE HARD CONTACTS WITH EXPECTED SUBSTANCE.

摘要

Material comprises a copolymer and a siloxane oligomer. The copolymer is made from at least one monomer component, selected from fluorine-contg. (meth)acrylate and silicone-contg. (meth) acrylate. The siloxane oligomer has polymerisable functional gps. at its molecular ends and is selected from cpds. of formulae (I) -(III). In the formulae, 1 is an integer between 10 and 200; the sum m1+m2 is an integer between 12 and 140 (m1 is at least 0, m2 is at least 1); n is an integer between 10 and 500; R1 is of formula (a) or (b). R2 is H or CH3; Ph is a phenyl group; R3 is -CH2-CH2-CH3-O-C(O)-C(R2)=CH2.
