    • Disclosed are a maleimide-α-alkylstyrene-based, heat-resistant bulk tetrapolymer and a preparation process thereof. More specifically, disclosed are a bulk tetrapolymer, comprising 5-60 wt % of an N-substituted maleimide monomer, 10-70 wt % of an α-alkylstyrene monomer, 5-50 wt % of an unsaturated nitrile monomer and 3-50 wt % of an aromatic vinyl monomer, as well as a continuous bulk polymerization process for preparing the same. The disclosed bulk tetrapolymer has a weight- average molecular weight (Mw) of 70,000-300,000 and a glass transition temperature of 150-200 °C, shows excellent high-temperature thermal stability and heat resistance and a remarkably low melt viscosity, and thus is excellent not only in processability, but also in productivity, processability, moldability and blendability, when it is blended with other resins. Also, the continuous bulk polymerization process is equipped with a devolatilizer and enables the bulk tetrapolymer to be produced at low cost and high efficiency.
    • 公开了马来酰亚胺-α-烷基苯乙烯类,耐热本体四元共聚物及其制备方法。 更具体地,公开了一种本体四元共聚物,其包含5-60重量%的N-取代的马来酰亚胺单体,10-70重量%的α-烷基苯乙烯单体,5-50重量%的不饱和腈单体和3-50重量% %的芳族乙烯基单体,以及用于制备芳族乙烯基单体的连续本体聚合方法。 所公开的本体四元共聚物的重均分子量(Mw)为70,000〜30000,玻璃化转变温度为150〜200℃,表现出优异的高温热稳定性,耐热性,熔融粘度显着降低, 当其与其它树脂混合时,不仅在加工性方面优异,而且在生产率,加工性,成型性和可混合性方面优异。 此外,连续本体聚合方法配备脱挥发物,能够以低成本和高效率制造本体四元共聚物。
