Abstract
The mechanism of TFE-P copolymer peroxide vulcanization in the presence of N, N - meta-phenylene-bis-maleimide (MPBM) was investigated by MDR Rheometer and DSC method. The results show that β-chain-scission reactions are present in TFE-P copolymer peroxide vulcanization, and the rate of β-chain-scission increase in high temperature. MPBM could improve the crosslinking efficiency and crosslinking rate. The mechanism is that TFE-P copolymer-MPBM radicals could form effective crosslinking and decrease the quantity of TFE-P copolymer radicals that would arise β-chain-scission reactions.
