Abstract: A typical phosphatide is lecithin. This invention relates to compositions and methods for forming polyether polyurethanes utilizing organophosphorus compounds selected from the class consisting of phosphatides and compounds of the formulas: ;(RO).sub.n R'.sub.3-n P(O)and(RO).sub.n R'.sub.3-n Pwherein R is a monovalent hydrocarbon group of at least 8 carbon atoms, R' is selected from the class consisting of hydrogen, hydroxyl and monovalent hydrocarbon groups, and n is an integer of 1 to 3, to impart the property of self-release from metal substrates, e.g., the walls of mold cavities in which they are formed and molded.

Abstract: This invention claims novel siloxane sulfates characterized by a trivalent linking group between the sulfate group(s) and the silicon atom(s). Such trivalent linking groups can be derived from, for example, trimethylolpropane. The novel siloxanes are anionic surfactants and are capable of lowering the surface tension of water, in some cases, as low as 20 dynes/cm. They are useful as wetting agents for polyethylene, cotton and other substrates. They are also useful as emulsifiers, foaming agents and detergent.

Abstract: This invention relates to novel polyoxyalkylene polymers characterized by olefinic endblocking groups in which the olefinic double bond is in the alpha position and is incapable of isomerizing or shifting to the beta or any other position. The novel polymers readily undergo addition reactions with siloxanes containing SiH to produce novel siloxane-polyoxyalkylene block copolymers that are useful as foam stabilizers for polyurethane foams. The olefinic double bonds undergo little side reactions during such addition reactions and so the product is relatively free of materials other than the block copolymer.

Abstract: This invention relates to polyurethane-polyurea cellular elastomers having excellent energy absorbing properties over a wide temperature range and at various impact speeds and, more particularly, to the production of such elastomers by reacting a polymer polyol, an aromatic polyamine and, an aromatic glycol with an organic polyisocyanate. The elastomers are useful as energy absorbing components in automobile bumpers and the like.

Abstract: This application relates to certain novel hydroxyalkenylsiloxanes that are particularly useful as foam stabilizers for rigid polyurethane foams. The novel hydroxyalkenylsiloxanes have critical siloxane molecular weights and are produced by an addition reaction involving hydrosiloxanes and acetylenically unsaturated alcohols that contain a terminal acetylenic bond which does not shift significantly during the reaction.
