Abstract (en)

[origin: US2004010072A1] The present invention provides an additive comprising A) a copolymer of ethylene and 8-21 mol % of at least one acrylic or vinyl ester having a C1-C18-alkyl radical and B) a comb polymer of at least one C8-C16-alkyl ester of an ethylenically unsaturated dicarboxylic acid and at least one C10-C20-olefin, wherein the sum Q <math-cwu id="MATH-US-00001"> <NUMBER>1</NUMBER> <MATH> <MROW> <MI>Q</MI> <MO>=</MO> <MROW> <MROW> <MUNDEROVER> <MO>∑</MO> <MI>i</MI> <MSTYLE> <MTEXT> </MTEXT> </MSTYLE> </MUNDEROVER> <MO>⁢</MO> <MROW> <MSUB> <MI>w</MI> <MROW> <MN>1</MN> <MO>⁢</MO> <MI>i</MI> </MROW> </MSUB> <MO>·</MO> <MSUB> <MI>n</MI> <MROW> <MN>1</MN> <MO>⁢</MO> <MI>i</MI> </MROW> </MSUB> </MROW> </MROW> <MO>+</MO> <MROW> <MUNDEROVER> <MO>∑</MO> <MI>j</MI> <MSTYLE> <MTEXT> </MTEXT> </MSTYLE> </MUNDEROVER> <MO>⁢</MO> <MROW> <MSUB> <MI>w</MI> <MROW> <MN>2</MN> <MO>⁢</MO> <MI>j</MI> </MROW> </MSUB> <MO>·</MO> <MSUB> <MI>n</MI> <MROW> <MN>2</MN> <MO>⁢</MO> <MI>j</MI> </MROW> </MSUB> </MROW> </MROW> </MROW> </MROW> </MATH> <mathematica-file id="MATHEMATICA-00001" file="US20040010072A1-20040115-M00001.NB"/> <image id="EMI-M00001" wi="216.027" he="23.04855" file="US20040010072A1-20040115-M00001.TIF" imf="TIFF" ti="MF"/> </MATH-CWU> of the averages by weight of the carbon chain distributions in the alkyl side chains of the olefins on the one hand and the fatty alcohols on the other hand is from 23 to 27, where w1 and w2 are the weight proportions of the individual chain lengths in the different monomers 1 and 2, and n1 and n2 are the side chain lengths, in the case of olefins without the originally olefinically bonded carbon atoms, of the individual species, and the running variables i and j are the individual side chain lengths in the particular monomer groups.
