Abstract: Copolymers (I) of hydrophobic (meth)acrylic esters (II) of mixts. of polyglycols and polyglycol ethers, with hydrophilic unsatd. comonomers (III) are claimed, in which most of the free OH gps. are etherified, esterified or converted into urethane gps., and/or the acid esterification catalyst is neutralised with amine. More specifically, (II) are obtd. by reaction of (meth) acrylic acid with alkoxylates of formula R1-O-(AO)x-H (IV), using an entraining agent to remove the water. R1=residue of alcohol, alkylphenol or a condensation prod. thereof with formaldehyde or acetaldehyde; AO=ethylene-, propylene- or 1,2-butylene-oxide residue or mixts. or blocks thereof; x=5-120. Partial etherification etc. as above is carried out before or after copolymerisation; pref. amine is tert. amine; pref. (III) have the formula R2CH=CR3R4, R2=H, COOH, COOC2H4OH, COOC2H4NEt2, CONH2, CN, Ph, OCOMe, CH2OH, NHCHO, COMe, COOEt, N-imidazolyl or N-pyrrolidinonyl; R3=H or COOH; R4=H or Me; at least one of R2 or R3 is a hydrophilic gp. Wt. ratio (IV):(III) is from 300:1 to 1:50. The process is claimed as such. OH gps. can be reacted with, e.g. MeI; Ac2O, etc. using H2SO4, etc. as catalyst; or PhNCO. Amine is e.g. Et3N, Bu3N, etc. (IV) is obtd. e.g. from EtOH, Bisphenol A, nonylphenol, etc. with alkylene oxide as above. (III) is e.g. (meth)acrylic acid, maleic anhydride, vinylpyrrolidone, etc.
