Abstract
Abstract 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.
