Aktiven Wasserstoff enthaltende Zusammensetzung, die einem geformten Artikel Entformungseigenschaften verleiht, und Verfahren zur Herstellung von polymeren Produkten aus der aktiven Wasserstoff enthaltenden Zusammensetzung.

摘要

This invention is directed to an active hydrogen-containing composition which provides mold release properties to a molded article, an internal mold release composition for preparing the active hydrogen-containing composition and a process for preparing molded polymeric products from the active hydrogen-containing composition by reacting it with a polyisocyanate, a polyisothiocyanate or a mixture thereof. The active hydrogen-containing compositions comprise (A) at least one metal salt of an organic material derived from a material containing at least one carboxylic acid group, phosphorus-containing acid group or boron-containing acid group or a mixture of such materials, wherein said metal is selected from Groups I or II of the Periodic Table of the Elements, aluminum, chromium, molybdenum, iron, cobalt, nickel, tin, lead, antimony or bismuth, (B) at least one active hydrogen-containing material having a plurality of either one or a combination of primary amine and secondary amine groups and, optionally, hydroxyl and/or thiol groups. The portion of component (B) containing primary amine groups and/or secondary amine groups and component (A) being present in a weight ratio of at least 2 : 1; and, optionally, (C) at least one organic material containing at least one carboxylic acid group, phosphorus-containing acid group or boron-containing acid group or a mixture of such materials, wherein at least one of components (A), (B) or (C) when present, contains at least one lipophilic group.
