Abstract
The glass transition characteristics of two groups of semiflexible copolymers incorporating meta linkages in the chain backbone have been investigated as a function of copolymer composition and crystallization history. The introduction of meta-phenylene linkages into the backbone of poly (phenylene sulfide) and poly (ether ketone ketone) leads to a loosening of the constraint which is imposed on the amorphous chains by the crystalline phase in these semicrystalline materials. This is manifested by a decrease in glass transition offset with increasing meta content, and the full mobilization of rigid amorphous material for less restrictive crystallization conditions.
