摘要： The invention relates to a polymer modification process wherein the rheology of one or more (co)polymers is modified by contacting the (co)polymer with at least one decomposing peroxide of the formula, 1 , wherein R1-3 are independently selected from substituted or unsubstituted hydrocarbyl groups. The modification process can be useful to obtain a modified resin or to enhance the flame retardancy of (expanded) styrenic resins.
摘要翻译：本发明涉及一种聚合物改性方法，其中一种或多种（共）聚合物的流变学通过使（共）聚合物与至少一种下式的分解过氧化物接触来改性，其中R1-3独立地选自取代或未取代的烃基。改性方法可用于获得改性树脂或增强（膨胀）苯乙烯树脂的阻燃性。

摘要： Thermal stabilization of halogeno-vinyl resins is achieved by the incorporation of one or more tetramercapto-tin compounds. The stabilization is improved by the addition of a crown compound, i.e. a cyclic polyether. The proportion of the crown compound is in general 10 to 200 parts by weight, preferably 25 to 100 parts, per 100 parts by weight of tin tetramercaptide.
摘要翻译：卤代乙烯基树脂的热稳定通过掺入一种或多种四聚巯基锡化合物来实现。通过加入冠状化合物即环状聚醚来改善稳定性。冠化合物的比例通常为每100重量份的四硫化锡锡为10〜200重量份，优选为25〜100重量份。

摘要： A method is provided for making cyclic carbonates of 2,2-bis(4-hydroxyphenyl)-1,1-dichloroethylene, such as the cyclic trimer, by effecting the polymerization of the aforementioned bis(4-hydroxyphenyl)dichloroethylene to a linear polycarbonate, and then agitating a solution of the resulting polycarbonate in the presence of a tertiary organic amine. The cyclic carbonates made by the aforementioned process are useful as flame retardants in polycarbonates.
