The present invention relates to stable compositions for the fungicidal equipment of thermoplastic polymers, in particular PVC, comprising thiabendazole, at least one iodine-containing fungicide and at least one epoxide and optionally further fungicidally active compounds, and also to methods for preparing these formulations and to uses thereof for the protection of thermoplastic polymers against attack and destruction by microorganisms. Moreover, the invention relates to mold-resistant PVC materials equipped with the compositions according to the invention.
A stabilizer composition comprising (A) a compound of the formula I
wherein R is (CH2-CH2-O-)n-R2; -CH2-CH(OH)-CH2-O-R2; or -CH(R3)-CO-O-R4; n is 0 or 1; R2 is C1-C13alkyl or C2-C20alkenyl or C6-C12aryl or CO-C1-C18alkyl; R3 is H or C1-C8alkyl; R4 is C1-C12alkyl or C2-C12alkenyl or C5-C6cycloalkyl; and (B) one or more compounds selected from (i) to (xlv) as defined in claim 1 is especially effective towards stabilizing organic materials against degradation induced by light, heat or oxidation.

The invention relates to low-dust granules of plastics additives, comprising
a) a phenolic antioxidant, an organic phosphite or phosphonite, a phosphonate, a sterically hindered amine or a UV absorber, individually, or a mixture of these compounds, and
b) at least one epoxy compound which is solid at room temperature.
The granules are particularly suitable for stabilizing polymers, especially polyolefins such as polypropylene or polyethylene.
o-Hydroxyphenyl-s-triazines of the formula I

in which n is 1 to 4 and R
1
to R
