ABSTRACT:
The invention relates to a combination of derivatives of dihydropyridine and .beta.-aminocrotonic acid derivatives intended for the stabilization of vinyl resins. The combination of a dihydropyridine derivative and a .beta.-aminocrotonic derivative gives rise to synergism of the stabilizing powers of each of those products.
