Continuous Copolymerization of β-methylstyrene-Acrylonitrile, α-Methylstyrene- Acrylonitrile

摘要

Two different approaches are proposed to calculate the chain sequence distribution in a-methyl styrene-acrylonitrile copolymer and AMS-AN-S (α-Methylstyrene-acrylonitrile-styrene) terpolymer, β-methylstyrene -acrylonitrile copolymer and BMS-AN-S (?-methylstyrene-acrylonitrile-styrene) terpolymer. Tube polymerization studies on the terpolymerization of AMS-AN-S using thermal initiation showed that molecular weight can be built at reasonable kinetic rates. One of the approaches is by using the probability model and expressing the results as geometric distribution neglecting effects due to Markov Statistics. The second approach is to use Monte Carlo simulations to calculate the chain sequence distribution.
