Copolymer containing acid building blocks and various types of polyether building blocks
摘要：
The invention relates to a copolymer comprising i) 3 to 40 mol % of an isoprenolpolyether derivative structural unit α ii) 3 to 40 mol % of a vinyloxypolyether derivative structural unit β and iii) 35 to 93 mol % of an acid structural unit γ, the structural units of the copolymer which belong to the vinyloxypolyether derivative structural unit β having longer side chains than the structural units which belong to the isoprenolpolyether derivative structural unit α.
摘要（中）：

本发明涉及一种共聚物，其包含i）3至40mol％的异戊二烯聚醚衍生物结构单元αii）3至40mol％的乙烯氧基聚醚衍生物结构单元β和iii）35至93mol％的酸性结构单元γ， 属于乙烯氧基聚醚醚衍生物结构单元β的共聚物的结构单元具有比属于异戊二烯聚醚衍生物结构单元α的结构单元更长的侧链。
