Abstract

Polymer mixtures made from two different polymer components and exhibiting LCST behavior are provided for use in applications which require temperature-dependent light permeability. The polymer mixtures P are made from: PA1 P1: from 98 to 2% by weight of poly-.alpha.-methylstyrene (PAMs); and PA1 P2: from 2 to 98% by weight of polyvinyl methyl ether (PVMe).
