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:The present invention discloses a preparation method of a synthetase for continuous monitoring of blood glucose. The method includes the preparation steps of step S1: hydroxylation of a glass bead; step S2: silanization of the glass bead; step S3: bonding of the glass bead to glucose; step S4: synthesis of a polymer particle on the surface of the glass bead to form a glucose synthetase; and step S5: separation of the highly specific glucose synthetase. According to the preparation method of a synthetase for continuous monitoring of blood glucose provided by the present invention, the glass bead is bonded to the glucose by activating the surface of the glass bead, and then bonded to a polymer to form the glucose synthetase. The artificial synthetase prepared by the method has low sensitivity to temperature and pH value, and can be directly used in a blood glucose electrochemical sensor.

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.

摘要:A method of synthesizing urethane-free polyfunctional acrylate compounds. The method includes reaction of a polyol with acrylic acid in the presence of an inhibitor. A catalyst may also be present. The catalyst may be an acid and the inhibitor may be a substituted phenol compound. Excess acid may be removed by adding a salt and excess water may be removed by adding a drying agent. The reaction converts alcohol groups of the polyol to acrylate groups to provide a radiation-curable polyfunctional acrylate compound. The reaction is applicable to polyols generally and provides a scalable high yield process for forming urethane-free polyfunctional acrylates over a wide range of molecular weights. Coatings made from the acrylate products exhibit modulus and tensile strength characteristics favorable for primary fiber coatings.

摘要:A method of forming a voided polymer includes forming a polymerizable composition containing a polymer precursor and a solid templating agent, forming a coating of the polymerizable composition, processing the coating to form a cured polymer material having a solid phase in a plurality of defined regions, and removing at least a portion of the solid phase from the cured polymer material to form a voided polymer layer.

摘要:Novel perfluoroalkyl group containing mercaptans and sulfides are disclosed having soil repellent properties if applied to substrates such as textiles, paper and leather and being useful as intermediates for the synthesis of soil repellent polymers. The adducts are obtained by the base or free radical catalyzed addition of hydrogen sulfide or mono- or polymercaptans to perfluoroalkyl group containing esters of fumaric, maleic, citraconic, mesaconic, itaconic, methylene malonic or aconitic acid.
