Abstract
A polymer composite material which comprises a first rigid polymeric material composed substantially of rigid molecular chains having an average chain length of 50 A or more, and a second polymeric material composed substantially of flexible molecular chains, wherein said first rigid polymeric material is present in an amount of 20% or less based on the total weight of polymeric material in said composite and said first material is uniformly dispersed in said second polymeric material in a microscopic region of 1 .mu.m or less.
