Title (EN) POLYMER MICROPARTICLES AND METHOD OF PRODUCING SAME
(FR) MICROPARTICULES DE POLYMÈRE ET LEUR PROCÉDÉ DE PRODUCTION
(JA) 重合体微粒子およびその製造方法
Abstract:
(EN) The present disclosure pertains to a method of producing polymer microparticles, said method comprising a step in which vinyl monomers are polymerized in the presence of a dispersion stabilizer in a hydrophilic solvent that dissolves the vinyl monomers and the dispersion stabilizer but does not dissolve the resultant polymer. Specifically, the present disclosure pertains to such a method of producing polymer microparticles, wherein the dispersion stabilizer contains a macromonomer that has a carboxyl group and an ethylenically unsaturated group in the molecular chain, and the macromonomer has an average of 1.4-2.5 ethylenically unsaturated groups per molecule and a molecular weight distribution of 2.0 or less.
(FR) La présente invention concerne un procédé de production de microparticules de polymère, ledit procédé comprenant une étape dans laquelle des monomères vinyliques sont polymérisés en présence d'un stabilisant de dispersion dans un solvant hydrophile qui dissout les monomères vinyliques et le stabilisant de dispersion mais ne dissout pas le polymère obtenu. Plus précisément, la présente invention concerne un tel procédé de production de microparticules de polymère, le stabilisant de dispersion contenant un macromonomère ayant un groupe carboxyle et un groupe à insaturation éthylénique dans la chaîne moléculaire, et le macromonomère ayant une moyenne de 1,4 à 2,5 groupes à insaturation éthylénique par molécule et une distribution de poids moléculaire de 2,0 ou moins.
(JA) 本開示は、分散安定剤の存在下に、ビニル単量体を、該ビニル単量体及び該分散安定剤を溶解するが、生成する重合体を溶解しない親水性溶媒中で重合する工程を備える、重合体微粒子を製造する方法に関する。本開示は、こうした重合体微粒子の製造方法において、上記分散安定剤が、分子鎖の途中にカルボキシル基及びエチレン性不飽和基を有するマクロモノマーを含有するものであり、上記マクロモノマーが、1分子当り平均して1.4~2.5個のエチレン性不飽和基を有し、且つ、その分子量分布が2.0以下となるようにする。
