Abstract

Polymers that have limiting viscosities, measured in tetrahydrofuran at 20.degree. C., of at least about 200 mL/g and that can be made by addition polymerization of a mixture of monomers containing: PA1 A. from 100--about 30 wt % of esters of acrylic acid and methacrylic acid with monohydric saturated aliphatic alcohols which contain from 1-22 C atoms; and PA1 B. up to about 70 wt % of monomers selected from the group consisting of: PA2 (1) unsaturated aliphatic carboxylic acids with 3-5 C atoms and their amides, PA2 (2) styrene and alkylstyrenes with 1-4 C atoms in their alkyl residues, PA2 (3) acrylonitrile, PA2 (4) vinyl esters of aliphatic C.sub.1-18 carboxylic acids, and PA2 (5) amino substituted esters of acrylic acid and methacrylic acid with monohydric alcohols having from 2-6 carbon atoms are highly effective anti-sling additives for textile lubricants.
