Abstract
The work proposed here will focus on the effects of crosslinking CBDO containing copolymers. A series of CBDO containing copolymers with aromatic diols will be made. These will incorporate CBDO, bisphenol A, phloroglucinol and terephthaloyl chloride by solution polymerization. Phloroglucinol, a trifunctional aromatic alcohol, will serve as an aromatic crosslinking agent. A series of crosslinked homopolymers will be made with bisphenol A and CBDO. Both will be crosslinked with phloroglucinol by solution polymerization. Both homopolymers will be made via solution polymerization. Thermal and mechanical tests will be utilized to characterize the structure/property relationships of these crosslinked polymers.
This study revealed that bisphenol A is a detrimental factor in these series of polymers. With the crosslinked polymers, the Tg and Td increase as the mol % of crosslinker increases. This is due to the fact that as the mol % crosslinker is increased, the overall % of bisphenol A decreases.
