Highly oxygen-permeable heat-resistant material

摘要

A highly oxygen-permeable heat-resistant material consisting essentially of a polymer obtained by polymerizing a polymerizable component containing a silicon-containing stilbene derivative of the formula (I): <IMAGE> (I) wherein each of R1 and R2 which are independent of each other, is a hydrogen atom or a group of the formula (II):-SipOp-1(CH3)2p+1(II)wherein p is an integer of from 1 to 8, provided that at least one of R1 and R2 is the group of the formula (II).
