摘要CTS-9616192 聚合物共混物主要通过熔融混合制备。 聚合物的增容作用发生在熔融加工过程中，特别是通过反应性挤出。 在该提议中，提出了形成和增容的替代方法;即，通过浓乳液的自增容。 在该方法中，由不同的单体制备两种浓乳液并进行部分聚合。 通过混合部分聚合的泡孔而不是熔体并使混合物进行完全聚合来形成共混物。 一些共聚物、嵌段共聚物或网络结构在后一聚合期间在泡孔表面附近产生，其实现所得共混物的“自增容”。 将研究两种类型的自动浓缩。 (1)两种浓缩乳液不含二乙烯基封端的大分子单体。 在这种情况下，增容通过在聚合物链附近形成共聚物来实现。 细胞的表面。 (2)两种浓缩乳液含有二乙烯基封端的大分子单体。 的 在这种情况下，增容通过形成增容剂来实现， 网络结构。 该方法的最大特点是共混聚合物和增容作用同时产生。

ABSTRACT CTS-9616192 Polymer blends are mostly prepared through melt-mixing. The compatibilization of the polymers occurs during melt-processing, especially via reactive extrusion. In this proposal, an alternative approach to the formation and compatibilization is proposed; namely, the auto-compatibilization via concentrated emulsions. In this method, two concentrated emulsions are prepared from different monomers and subjected to partial polymerization. A blend is formed by mixing the partially polymerized cells instead of melts and subjecting the mixture to complete polymerization. Some copolymers, block copolymers or network structures are generated during the latter polymerization near the surface of the cells, which achieve the "auto-compatibilization" of the resulting blend. Two types of auto-concentration will be investigated. (1) The two concentrated emulsions do not contain di-vinyl-terminated macromonomers. The compatibilization is achieved in this case by the formation of copolymers near the surface of the cells. (2) The two concentrated emulsions contain di-vinyl-terminated macromonomers. The compatibilization is achieved in this case via the formation of compatibilizers with network structures. The most distinctive feature of the method is that the blended polymers and the compatibilization are generated simultaneously.
