    摘要： An insulated glass sealant having the best characteristics of polysulfides and polyurethanes rather than the worst is made from a polysulfide-based polyurethane prepared by a one-step procedure wherein a randomly copolymeric hydroxyl-terminated polysulfide polyacetal is reacted with a polyisocyanate at a ratio of from about 1:1 to about 1:1.2 on an equivalents basis. The copolymeric hydroxyl-terminated polysulfide polyacetal is made by the condensation of formaldehyde with a mixture of a dithiodialkylene glycol and an aliphatic or cycloaliphatic diol.

    摘要： 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.
