Biocide batches based on cross-linked native oils, process for the production thereof and use thereof in thermoplastic molding compositions

A process for producing biocide batches comprising the mixing in mixing units of a mixture of

• (a) 10 to 99.9 wt. % of factice or epoxidized and then cross-linked esters of at least dihydric alcohols and unsaturated fatty acids or cross-linked native oils or mixtures thereof and
• (b) 0.1 to 90 wt. % of conventional biocides at temperatures of from 20 to 100° C.

Stabilizers against the degradation of thermoplastic molding compositions by insects, termites, fungi, microbes and bacteria comprising a mixture of

• (a) 10 to 99.9 wt. % of factice or epoxidized and then cross-linked esters of at least dihydric alcohols and unsaturated fatty acids or cross-linked native oils or mixtures thereof and
• (b) 0.1 to 90 wt. % of conventional biocides.
