  • A process for the production of carboxylated latexes by the selective monomer addition and polymerization
    申请人:THE GOODYEAR TIRE & RUBBER COMPANY
    公开号:EP0538722A1
    公开(公告)日:1993-04-28
    The present invention relates to a free radical emulsion polymerization process. The latex is prepared by polymerizing (a) at least one conjugated diene, (b) at least one non-carboxylic vinyl aromatic or aliphatic comonomer selected from the group consisting of styrene, α-methyl styrene, p-methyl styrene, vinyl toluene, acrylonitrile, methacrylonitrile, vinylidene chloride, ethyl acrylate, butyl acrylate, vinyl pyridine, methylmethacrylate, hexylacrylate, 2-ethyl hexyl acrylate or mixtures thereof, and (c) at least one ethylenically unsaturated carboxylic acid monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, 3-carboxyethylacrylate, itaconic acid or mixtures thereof. The process of the present invention is characterized by (a) initially polymerizing the non-carboxylic comonomer in the presence of the unsaturated carboxylic acid and in the absence of any conjugated diene to a conversion of 3 to 12 percent to form a partially polymerized latex; and thereafter (b) copolymerizing the conjugated diene with the unreacted non-carboxylic comonomer in the partially polymerized latex. The present process mitigates the formation of codimers of the conjugated diene and non-carboxylic comonomer. The present process also provides a latex having unique film forming characteristics and polymer morphology leading to unique film stiffness and stress-strain relationship.
    本发明涉及一种自由基乳液聚合工艺。胶乳是通过聚合 (a) 至少一种共轭二烯,(b) 至少一种非羧基乙烯基芳香族或脂肪族共聚单体而制备的,该共聚单体选自苯乙烯、α-甲基苯乙烯、对甲基苯乙烯乙烯基甲苯丙烯腈甲基丙烯腈、亚乙烯基丙烯酸乙酯丙烯酸丁酯乙烯基吡啶甲基丙烯酸甲酯丙烯酸己酯、丙烯酸 2-乙基己酯或它们的混合物、(c) 至少一种乙烯基不饱和羧酸单体,选自丙烯酸甲基丙烯酸马来酸富马酸、3-羧乙基丙烯酸酯、衣康酸或其混合物组成的组。本发明工艺的特点是:(a) 非羧酸共聚单体在有不饱和羧酸和没有任何共轭二烯的情况下进行初始聚合,转化率为 3-12%,形成部分聚合胶乳;然后(b) 共轭二烯与未反应的非羧酸共聚单体在部分聚合胶乳中进行共聚。本工艺减少了共轭二烯和非羧酸共聚单体的形成。本工艺还提供了一种具有独特成膜特性和聚合物形态的胶乳,从而形成独特的薄膜刚度和应力应变关系。

  • DECARBOXYLASE AND METHOD FOR PRODUCING UNSATURATED HYDROCARBON COMPOUND USING SAME
    申请人:Riken
    公开号:EP3660156A1
    公开(公告)日:2020-06-03
    With the aim of providing a method allowing production of an unsaturated hydrocarbon compound such as butadiene with high productivity and an enzyme used in the method, the present inventors introduced mutations involving amino acid replacement into various positions of a ferulic acid decarboxylase, and prepared multiple modified forms of the enzyme. Then, the present inventors evaluated those modified forms in terms of the catalytic activity for the production of butadiene, and found as a result that the catalytic activity was improved in the case where, for example, the amino acid at position 395 was glutamine, histidine, asparagine, leucine, isoleucine, methionine, lysine, serine, arginine, tyrosine, or phenylalanine.
