COPOLYMERS BASED ON STYRENE AND ESTERS OF (METH)ACRYLIC ACID, AND THEIR USE IN FACADE PAINTS CONTAINING PETROL, OR IN DETERGENTS

摘要

Gasoline-soluble copolymers containing, as copolymerized units, (A) from 10 to 40% by weight of styrene, (B) from 10 to 50% by weight of tert.-butyl acrylate and/or vinyl pivalate, (C) from 20 to 40% by weight of isobutyl methacrylate, (D) from 5 to 20% by weight of acrylic acid esters and/or methacrylic acid esters of alkanols of 10 to 20 carbon atoms and (E) from 0 to 5% by weight of monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids of 3 to 5 carbon atoms and/or their beta -hydroxyalkyl esters and/or monoalkyl esters of the dicarboxylic acids, the amount of component (D) being from 20 to 50% by weight of that of component (A), and the sum of the percentages of A to E being 100, are particularly suitable for use as binders for gasoline-containing masonry paints and renders.
