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.

摘要/ ABSTRACT摘要：CTS-9616192聚合物共混物多采用熔融混合制备。聚合物的相容性发生在熔融加工过程中，特别是通过反应挤出。在本提案中，提出了形成和相容的替代方法；即通过浓乳剂进行的自相容。在这种方法中，由不同的单体制备两种浓缩乳液并进行部分聚合。通过混合部分聚合的细胞而不是熔体并使混合物完全聚合而形成共混物。在后一种聚合过程中，在细胞表面附近产生一些共聚物、嵌段共聚物或网络结构，从而实现了所得到的共混物的“自相容”。本文将研究两种类型的自动浓缩。(1)两种浓缩乳剂不含二乙烯基端大单体。在这种情况下，通过在细胞表面附近形成共聚物来实现相容性。(2)两种浓缩乳剂均含有端二甲乙烯基高分子单体。在这种情况下，增容是通过形成具有网络结构的增容剂实现的。该方法最显著的特点是共混聚合物和增容同时产生。
