Description

ABSTRACT:
The crystallinity of poly(1,4-cyclohexanedimethyl 1,4-cyclohexanedicarboxylate) is enhanced by the incorporation of amide units, preferably derived from such compounds as 1,6-bis(4-carbomethoxycyclohexylcarboxamido)hexane. Crystallization temperatures increase, as do heats of crystallization.
