摘要:Wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin microcellular products, obtained by the reaction of (a) a polyisocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, and at least one urethane, $(1,5)omicronp. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient of friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, in particular, two and three component systems are useful in molding operations, e.g., manufacture of shoe soles.

摘要:Synthesis of integral skin microcellular polyurethane elatomers by reacting hydroxyl-terminated aliphatic polyesters with symmetrical diisocyanates, prepolymers of these isocyanates such as derived from p,p'-diphenylmethane diisocyanate and an aliphatic glycol and mixtures thereof, these are polymerized in the presence of an organic blowing agent, and one or more plasticizers such as of the formulae further enhancement of the results is brought about by the presence of catalysts and cell regulating agents, such as dimethylpolysiloxanes; the obtained elastomers are useful, such as for shoe soles and in the manufacture of other products, e.g., vibration dampening devices, floatation devices, gaskets and the like.
