A method for producing a (meth)acrylic polymer particle comprises polymerizing a monomer (X) having a (meth)acryloyl group to produce a polymer particle, and polymerizing a monomer mixture (Y) in the presence of the polymer particle, in which the monomer (X) is 90 to 99.9% by mass and the monomer mixture (Y) is 0.01 to 10% by mass in terms of the ratio among monomer raw materials to be supplied for polymerization; and the monomer mixture (Y) comprises 1 to 80% by mol of a monomer (a) having a basic nitrogen atom or having a blocked isocyanate as a functional group, 5 to 80% by mol of a (meth)acrylate monomer (b) of at least one alcohol selected from the group consisting of an aliphatic alcohol having 2 or more carbon atoms, an aromatic alcohol, and a cyclic alkyl alcohol, and 0 to 94% by mol of a monomer (c) other than the monomer (a) and the monomer (b).
一种生产(甲基)丙烯酸聚合物颗粒的方法包括聚合具有(甲基)丙烯酰基的单体(X)以生产聚合物颗粒,以及在聚合物颗粒存在的情况下聚合单体混合物(Y),其中单体(X)的质量百分比为90至99.9%,单体混合物(Y)的质量百分比为0.按聚合用单体原料的比例计算,单体(X)的质量百分比为 90%至 99.9%,单体混合物(Y)的质量百分比为 0.01%至 10%;单体混合物 (Y) 包括 1 至 80% (以摩尔计)具有碱基氮原子或具有封端异氰酸酯作为官能团的单体 (a),5 至 80% (以摩尔计)至少一种选自具有 2 个或更多碳原子的脂肪族醇、芳香族醇和环烷基醇的醇的(甲基)丙烯酸酯单体 (b),以及 0 至 94% (以摩尔计)除单体 (a) 和单体 (b) 之外的单体 (c)。
