摘要： This invention pertains to a composition and a process for preparing a closed cell alkenyl aromatic polymer foam having enlarged cell size, comprising one or more alkenyl aromatic polymers, one or more substantially random interpolymers, one or more blowing agents having zero ozone depletion potential and optionally one or more co-blowing agents, and optionally, one or more nucleating agents and optionally, one or more other additives. This combination allows the manufacture of closed cell, low density alkenyl aromatic polymer foams of enlarged cell size, when blowing agents of relatively high nucleation potential are employed. When such blowing agents are used with alkenyl aromatic polymers in the absence of the substantially random interpolymers, small cell foams result.

摘要： Polymer compositions comprise a (i) silane-fknctionalized polymer, e.g., a polyethylene grafted with vinyl triethoxy silane, (H) polyfunctional alcohol e.g., a,a,a',a'~ tetramethyl-I,3-benzenediethanol and, optionally, (iii) acid, e.g., an alkylated aryl disulfonic acid. The use of polyfunctional alcohols in the absence of a strong acid yields a light- crosslinking of the silane-functionalized polymer and this, in turn, provides a polymer melt with improved extensional properties such as elongational viscosity and melt strength. The use of a polyfunctional alcohol in combination with a blocked strong acid provides a slow rate of crosslinking during melt processing and a high degree of ultimate crosslinking after the polymer composition has been shaped or molded.
摘要翻译：聚合物组合物包含（i）硅烷官能化聚合物，例如用乙烯基三乙氧基硅烷接枝的聚乙烯，（H）多官能醇，例如a，a，a'，a'〜四甲基-1,3-苯二甲醇，（iii）酸，例如烷基化芳基二磺酸。在不存在强酸的情况下使用多官能醇产生硅烷官能化聚合物的轻交联，这又提供了具有改进的拉伸性能如伸长粘度和熔体强度的聚合物熔体。使用多官能醇与封闭的强酸组合提供了在熔融加工过程中缓慢的交联速率，以及在聚合物组合物成型或模制之后的高度极限交联。
