摘要: An alternative polyurethane composition is provided which comprises a reaction product of an azidated polyol and a poly(alkynyl carbamate) prepolymer reacted at a temperature of from 20° C. to 120° C., wherein the poly(alkynyl carbamate) prepolymer comprises a reaction product of a polyisocyanate and a stoichiometric equivalent of an alkynol of the formula (I), HC≡C—R1R2—OH (I), and wherein R1 is an electron-withdrawing group selected from the group consisting of carbonyl, ester, amide, and urethane and R2 is a linear or branched alkyl chain having from 1 to 15 carbon atoms. The inventive alternative polyurethane composition position may be used to provide adhesives, sealants, films, elastomers, castings, foams, and composites.

摘要: A method of forming a three-dimensional object, wherein said three-dimensional object is an insert for use between a helmet and a human body, is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

摘要: This invention relates to polymer polyols which comprise one or more base polyols, at least one preformed stabilizer, one or more ethylenically unsaturated monomers, and, in the presence of at least one free radical polymerization catalyst, and optionally, one or more polymer control agents. The base polyol of these polymer polyols comprises one or more amine initiated polyols. The present invention also relates to processes for preparing these polymer polyols, to foams prepared from these polymer polyols, and to processes for producing foams from these polymer polyols.
