  • Aminoplast resin compositions
    Patent number: 4452934
    Abstract: Aminoplast resin compositions formed by reaction of an amino-aldehyde precursor in the presence of a cationic surfactant and a hydrocarbon product consisting essentially of components having average carbon chain lengths of about 12 or higher are provided. The aminoplast resin compositions have particular applicability as softening agents for paper and other cellulosic products.

  • Associations for stabilizing vinyl resins
    Patent number: 4388430
    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.
