Copolymers based on acid derivatives mono- or unsaturated carboxylic and oxyalkylene glycol-alkenyl ethers, processes for their preparation, and their use.

摘要

Copolymers based on acid derivatives mono- or unsaturated carboxylic and oxyalkylene-alkenyl ethers, characterized by containing a) 25 to 98.99% by mole of structural units of the formulas Ia and / or Ib and / or Ic (see formula) where R 1 = hydrogen or an aliphatic hydrocarbon radical having 1 to 20 carbon atoms CX = oma, O- (CmH2mO) nR 2, -NH- (CmH2mO) nR 2, M = hydrogen, a cation metal mono- or di-valent, an ammonium ion, organic amine radical, a = 1/2 or 1, R 2 = hydrogen, an aliphatic hydrocarbon radical having 1 to 20 carbon atoms, cycloaliphatic hydrocarbyl radical 5 to 8 carbon atoms, an aryl radical having 6 to 14 C atoms, which may optionally be still substituted, Y = O, NR 3 m = 2 to 4, and n = 0 to 200, b) from 1 to 48.9 mol% of structural groups of general formula II (See formula) representing ...
