Thermoplastische Spritzgussmasse

摘要

Mixtures of (a) PVC contg. at least 85% chemically combined vinyl chloride (K index 40-80), (b) a thermoplastic graft copolymer formed by grafting a mixt. of vinyl and/or vinylidene monomers on a latex of synthetic elastomer with high content of chemically combined dienic hydrocarbons, the graft copolymer contg. 30-60% dienic hydrocarbon, 3-52.5% styrene type cpd. and 10-17.5% acrylonitrile type cpd., and (c) a plsticiser and fluidifier consisting of epoxideised soya oils and/or esters of 1-20C carboxylic acids with 2-20C aliphatic alcohols pref. epoxidised in the alcohol and/or acid chain. Ratio (a):(b):(c) is 51-98%:1-40%:1-15%.
