Ring-opening polymerization of trimethylene carbonate (TMC) with a rare earth calixarene compound as catalysthas been studied for the first time. The effect of
Macroreticular bead PAN/PVC IPN resins with cyano and chloro groups were synthesized by interpenetrating polymerization of acrylonitrile, or acrylonitrile and d
The effects of HDPE matrix toughness on the brittle-ductile transition of HDPE/CaCO<sub>3</sub>blends are investigated. Not all HDPE can be toughened by CaCO<su
