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 :Methods for the preparation of targeting agent functionalized diblock copolymers for use in fabrication of therapeutic targeted nanoparticles

摘要:This application provides nanoparticles and methods of making nanoparticles using pre-functionalized poly(ethylene glycol)(also referred to as PEG) as a macroinitiator for the synthesis of diblock copolymers. Ring opening polymerization yields the desired poly(ester)-poly (ethylene glycol)-targeting agent polymer that is used to impart targeting capability to therapeutic nanoparticles. This “polymerization fromâ€? approach typically employs precursors of the targeting agent wherein the reactivity of functional groups of the targeting agent is masked using protecting groups. Also described is a “coupling toâ€? that utilized the poly(ethylene glycol)-targeting agent conjugate where the targeting agent remains in its native un-protected form. This method uses “orthogonalâ€? chemistry that exhibit no cross reactivity towards functional groups typically found within targeting agents of interest.
