The invention relates to thermoplastic moulding compositions based on vinyl chloride polymers and containing, as stabiliser, 0.1 to 5 % by weight of all aminouracil of the formula I (I) Image wherein R1 is hydrogen and R and R3 are C2-C4 alkyl groups. The addition of such aminouracils gives vinyl chloride polymers which are very well protected against heat-induced degradation. The aminouracils cause no haze in the polymer to be protected.
