标 题 :Thiourethane polymers, method of synthesis thereof and use in fused filament fabrication printing
发明人：ELLSON GREGORY T; LUND BENJAMIN R; VOIT WALTER
权利人:BOARD OF REGENTS THE UNIV OF TEXAS; ADAPTIVE 3D TECH
摘要:A thermoplastic thiourethane polymer comprising a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. The first type of monomer includes two or more thiol functional groups and the type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anhydrous aprotic solvent-dissolved anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7.

摘要:A semi-crystalline thiourethane polymer. The semi-crystalline thiourethane polymer comprises a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. Each of the first type of monomer includes two or more thiol functional groups and each of the second type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7, produced by photo-initiated decomposition of a photolatent base. A method of synthesizing, and polymer jetting and stereolithography methods of manufacturing a polymer part, are also disclosed.

标题:Synthesis of aqueous, anionic, amino acrylate polymers

摘要:Disclosed is a method of making aqueous, anionic amino polymers in water from olefinically unsaturated monomers including amine-containing monomers, but substantially without the inclusion of acid-group containing monomers. The polymerization of the amino polymer is carried out in the presence of a carboxy functional azo initiator dissolved in water by neutralization of acid groups present on the initiator. The polymer is useful in single-package or two-package coating compositions having pH above 7.0 that may be cured with polyisocyanates or polyepoxides.

摘要:This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
