专利汇可以提供Production of acrylonitrile copolymer专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain a copolymer which is low in transparency loss and can give flame-retarding fiber excellent in gloss, by coplymerizing acrylonitrile in water as medium in the presence of a small amount of a sulfonic acid group- containing unsaturated monomer having a surface activity.
CONSTITUTION: 40W68wt% acrylonitrile, 58W30wt% vinyl chloride or vinylidene chloride and 0.4W3wt% sulfonic acid group-containing unsaturated monomer having a surface activity [e.g., a compound of formula I or II (wherein R
1 and R
2 are each H, CH
3 or the like, R is C
n H
2n+1 and n is 9W18, M is Na or the like)] are fed to a reaction system. These monomers are copolymerized with each other in water as a medium in the presence of a water-soluble redox initiator system (e.g., a combination of ammonium persulfate with acid sodium sulfite) to obtain the purpose acrylonitrile copolymer. A flame-retarding acrylic fiber is obtained by spinning this copolymer.
