Abstract

Novel p-hydroxybenzoic esters of formula (I) (where R1 is tert. alkyl. R2 is H, alkyl, alkoxy, cycloalkyl, cycloalkylalkyl, phenyl opt. substs. by alkyl or arylalkyl opt. substd. by alkyl or halogen in the aryl ring. R3, R4 are H, alkyl. Y is O or 1. p is 1 or 2. R is a group of formula (II) or when y is 1, also a group of formula (III) where R5, R6 are H, alkyl X1, X2 are H or together form a group -O-, -S-, -SO-, -SO2-, -N(R7), or -C(R11)2-with R7 alkyl or phenyl and R11 H, or alkyl. Y is -O-, -S-, -SO-, S32-, or -C(R10)(R11) where R is H, methyl ethyl. R8, R9 are H, halogen, cycloalkyl, phenyl, carboxy or carboxylic ester. Rings A and B are opt. satd. and when p = 2 the links are on separate rings of (II) or (III). are used for stabilising org. matls., partic. polypropylene and polyethylene, against ultra-violet light.
