Abstract

Abstract Translated from German Copolymerisate aus 2 bis 3 C-Atome enthaltenden monoolefinisch ungesättigten Carbonsäuren und Styrol mit mittleren Molekulargewichten von 400 bis 4000, die aus a) 37 bis 45 Gew.% der ungesättigten Carbonsäuren, b) 55 bis 63 Gew.% Styrol und c) 0 bis 10 Gew.% anderen hydrophoben monooiefinisch ungesättigten Monomeren bei 200 bis 400°C durch kontinuierliche Massepolymerisation in Abwesenheit von Polymerisationsimitiatoren und Reglern hergestellt sind, und ihre Verwendung zur Herstellung von wäßrigen Papierlacken. Copolymers of 2 to 3 carbon atoms containing monoolefinically unsaturated carboxylic acids and styrene with average molecular weights of 400 to 4000, which consist of a) 37 to 45% by weight of the unsaturated carboxylic acids, b) 55 to 63% by weight of styrene and c) 0 to 10% by weight of other hydrophobic monooiefinically unsaturated monomers at 200 to 400 ° C. are produced by continuous bulk polymerization in the absence of polymerization initiators and regulators, and their use for the production of aqueous paper varnishes.
