Abstract: A dispersion in an aromatic polyisocyanate of a reaction product of the polyisocyanate and an amine having the formula: ##STR1## wherein Q represents hydrogen or hydrocarbyl and R represents a hydrocarbyl radical selected from radicals of the formulae: ##STR2## or wherein R and Q together with the attached nitrogen atom form a piperidine, morpholine or pyrolidine ring bearing a hydrocarbyl radical on at least one of the carbon atoms adjacent to the nitrogen atom.

Abstract: 11-[4-[2-(2-Hydroxyethoxy)ethyl]-1-piperazinyl]dibenzo[b,f][1,4 ]thiazepine is disclosed as a neuroleptic with a much reduced incidence of side effects such as acute dystonia and dyskinesia and tardive diskinesia.

Abstract: A polyisocyanate composition, suitable for use in the production of elastomers by the RIM process, said composition being the product of reacting an alcohol and/or thiol having an average hydroxyl and/or thiol functionality of from about 1.5 to about 4 and an average hydroxyl and/or thiol equivalent weight of at least 500 with at least 2 equivalents, per hydroxyl and/or thiol equivalent, of an organic polyisocyanate under such conditions that at least about 20% of the initially formed urethane and/or thiourethane groups are converted to allophanate and/or thioallophanate groups.

Abstract: Modified organic isocyanate composition containing urea and/or biuret groups and/or salts of these groups, obtained from the reaction of a blocked polyamine composition and an unblocked isocyanate composition.

Abstract: Polyureas are prepared from a system of (A) a polyisocyanate; and (B) a mixture of polyamines containing (i) from 60 to 25 percent by weight of the mixture of an aromatic polyamine; and (ii) from 40 to 75 percent by weight of the mixture of an aliphatic polyamine.

Abstract: Polymers having substituted urea groups, and molded objects therefrom, can be made by reacting, in a reaction injection molding (RIM) process, a composition comprising (A) a polyisocyanate and (B) a mixture comprising an imino functional resin and a chain extender. The chain extender may also be imino functional.

Abstract: A bowling ball having at least an outer portion fabricated from the reaction of reactants comprising(i) a polyisocyanate,(ii) an active hydrogen-containing compound having an average functionality of at least 2.0, and(iii) a slip agent compound containing a moiety which imparts lubricity to said ball, said slip agent compound also having at least one active hydrogen-containing group which is reactive with isocyanate groups, said slip agent compound being present in an amount between about 0.5 and about 5 weight percent based on the weight of (i) and (ii),the ratio of (i) to the total of (ii) plus (iii) being such that the reaction is conducted at an isocyanate index between about 0.90 and about 1.30.

Abstract: A system for use in making molded polyurethane objects by an open or closed casting process, said system comprising(A) an aromatic polyisocyanate; and(B) an active hydrogen-containing composition comprising(i) a polyhydric alcohol having an average molecular weight in the range of about 1000 to about 8000 and an average functionality of about 2 to about 4;(ii) a polyhydric alcohol having 2 to 12 carbon atoms and an average functionality of about 2 to about 3; and(iii) a secondary monoamine of the formulaR--NH--R'wherein R and R' are independently saturated aliphatic groups having 1 to 20 carbon atoms, provided that said secondary monoamine contains at least 4 carbon atoms.
