new 2 - phenyl - indolderivat intended as stabilizers for polymers and vinylsampolymerer and seen for framstellning of these stabilizers.

摘要

New stabilizers of polymers and co-polymers of vinyl chloride, the said stabilizers being 2-phenyl-indole derivatives corresponding to the formula: IMAGE wherein R represents a phenyl radical, an amino group, optionally substituted by an acetyl or benzoyl radical, a mercapto group, optionally substituted by a branched-or straight-chain alkyl group containing from 1 to 12 carbon atoms or by a cyclohexyl radical, a carboxyl radical, a radical represented by the formula:
