ABSTRACT:
A latex having a reduced amount of 4-phenylcyclohexene is obtainable by reacting A) 30–90% by weight of at least one ethylenically unsaturated monomer; B) 70–10% by weight of a diene; C) 1–10% by weight of α,β-unsaturated carboxylic acids, carboxylic acid nitriles, carboxylic acid amides, or mixtures thereof; and D) an auxiliary, an additive or mixtures thereof. The reaction follows a gradient regime for components A and B.
