The present invention provides an improved process for making diphosphaspiroundecanes and product-by-process, wherein the process comprises reacting a hydroxyl-substituted organic compound, phosphorous trichloride and pentaerythritol to form an organic-substituted diphosphaspiroundecane such that formation of said organic-substituted diphosphaspiroundecane takes place in the presence of a tri-n-alkylamine having n-alkyl moieties such that each n-alkyl moiety has at least three carbon atoms. The present invention is also directed to bis-3,9-(2,6-di-t-alkyl-4-alkylphenoxy)-2,4,8,10-tetroxa-3,9-diphosphasprio[5.5]undecanes and polymer composition containing an effective amount of same.
本发明提供了一种改进的制造二硫环十二烷和产品的工艺,其中该工艺包括使羟基取代的有机化合物、三氯化磷和季戊四醇反应,以形成有机取代的二硫环十二烷,从而使所述有机取代的二硫环十二烷的形成在具有n-烷基的三正烷基胺存在下进行,所述n-烷基使每个n-烷基具有至少三个碳原子。本发明还涉及双-3,9-(2,6-二烷基-4-烷基苯氧基)-2,4,8,10-四-3,9-二磷杂螺环[5.5]十一烷和含有有效量二磷杂螺环[5.5]十一烷的聚合物组合物。
