Mechanical and Morphological Properties of the Copolycarbonate of Bisphenol A and 4, 4'-Dihydroxydiphenyl

摘要

A copolycarbonate (DOD-co-PC) (1) of bisphenol A and 4, 4'-dihydroxydiphenyl (DOD) with defined amounts of DOD has an outstanding balance of optical, mechanical, thermal and impact properties. In particular, it has high light transmission, high glass transition and heat-distortion temperatures, and high notched Izod impact strength at thick section and low temperatures, Furthermore, it is unusually resistant to embrittlement after heat aging. For further understanding of the structure property relationships, DOD-co-PC with different amounts of DOD are investigated.
