| abstract | PCT No. PCT/EP97/00176 Sec. 371 Date Sep. 25, 1998 Sec. 102(e) Date Sep. 25, 1998 PCT Filed Jan. 16, 1997 PCT Pub. No. WO97/28234 PCT Pub. Date Aug. 7, 1997The invention concerns demulsifiers and methods of demulsifying based on polyalkyl (meth)acrylated co-oligomers or copolymers, CNP, built up from the following components consisting essentially of: A) 10 to less than 60 weight % of alkyl (meth)acrylic acid esters (CH2=C(R)C(O)OR1), wherein the alkyl group is an optionally branched alkyl group having 1 to 32 carbon atoms; B) more than 40 to 90 weight % (meth)acrylic acid esters of alkoxylated radicals (CH2=C(R)C(O)O(RA)n-(RB)m-R2 ), wherein R2 has 1 to 50 carbon atoms and is an optionally branched alkyl group, a cycloalkyl group, aryl group, or an alkaryl group; RA and RB represent the alkoxylation radicals a) -CH2-CH2-O-, b) -CH(CH3)-CH2-O-, or c) -CH2-CH(CH3)-O-; with the proviso n+m is a number between 3 and 200 and any individual member a), b), or c) does not exceed 100; and C) 0 to less than 40 weight % of a 1-alkene with 4 to 32 carbon atoms, with the proviso that the components A)+B)+C) add up to 100 weight %. |
