copolímero contendo blocos de construção ácida e vários tipos de blocos de construção de poliéter.

摘要

The invention relates to a copolymer comprising i) 3 to 40 mol % of an isoprenolpolyether derivative structural unit alpha ii) 3 to 40 mol % of a vinyloxypolyether derivative structural unit beta and iii) 35 to 93 mol % of an acid structural unit gamma, the structural units of the copolymer which belong to the vinyloxypolyether derivative structural unit beta having longer side chains than the structural units which belong to the isoprenolpolyether derivative structural unit alpha.
