摘要： A process is described which reduces the amount of bloom and/or plate-out of phosphite antioxidants during polymer processing by the addition of at least one polyethylene glycol (or blends thereof) or polycaprolactones (or blends thereof) having an average molecular weight of approximately 1,000 to 20,000, most preferably between 4,000 to 10,000.

摘要： A process to stabilize a polymer is described utilizing the step of adding a phosphite reaction product of a triphenyl phosphite or lower molecular weight trialkyl phosphite (e.g., trimethyl phosphite) or triaryl phosphite, with from approximately 1 to 2 moles of preferably a paracumyl phenol, and with from approximately 1 to 2 moles of at least C12-20 carbon alkyl or C12-20 alkenyl alcohol. In one embodiment of the invention, the phosphite reaction product is formula (I) wherein R1 is independently selected from the group consisting of H and C1-2 alkyls; R2 is independently selected from the group defined previously for R1; x is an integral value ranging from 0 to 4 inclusive; y is an integral value ranging from 0 to 4 inclusive; n is an integral value ranging from 1 to 2; R3 is independently selected from the group consisting of C12-20 alkyl or C12-20 alkenyl; R4 is independently selected from the group consisting of C1-10, alkyl and C9-15 arylalkyl; R5 is independently selected from the group defined previously for R4.
摘要翻译： 使用将亚磷酸三苯酯或低分子量亚磷酸三烷基酯（例如亚磷酸三甲酯）或亚磷酸三芳基酯与亚磷酸酯反应产物加入约1至2摩尔优选对枯基苯酚的步骤来描述稳定聚合物的方法， 和约1-2摩尔的至少C 12-20碳烷基或C 12-20烯基醇。 在本发明的一个实施方案中，亚磷酸酯反应产物是式（I），其中R 1独立地选自H和C 1-2烷基; R2独立地选自以下针对R1定义的基团; x是从0到4的整数值; y是从0到4的整数值; n是从1到2的整数值; R3独立地选自C12-20烷基或C12-20烯基; R 4独立地选自C 1-10，烷基和C 9-15芳烷基; R5独立地选自先前针对R4定义的基团。
