The copolymerizations of acrylates including:methyl acrylate(MA),methyl methacrylate(MMA), isobornyl methacrylate(IBMA)with different N-arylmethacry- lamiues including:N-phenylmethacrylamide(N-phMA ),N-p-Tolylmethacrylamide(N- p-TMA),N-o-Tolymethcryhmide (N-o-TMA).
用 ̄1H-NMR方法测定了共聚物的组成,估算了共聚体系中各单体的竞聚率,比较了各种单体的反应活性。
The kinetics of VDC-MA suspension copolymenzation with VDC as main component was studied.
对高VDC含量的VDC-MA悬浮共聚体系进行了研究,提出高VDC含量的VDC-MA共聚体系的高转化率速率模型:dc/dt=ac~β[I]~r_o exp(-γk_dt),研究了单体组成、引发剂浓度、聚合温度对聚合速率的影响,求得VDC-MA配比为93:7时模型参数与聚合温度的关系,此模型可以使用到85%转化率。
