ABSTRACT:
Synthetic resins such as polyolefins, vinyl chloride polymers, ABS polymers, ethylene-vinyl acetate copolymers and polyesters are stabilized against deteriorating influences with new stabilizer compositions comprising certain hydroxyphenylalkylenephosphonic acid esters of polycarbocyclic polyhydroxy compounds having the general formula (1) ##STR1## (wherein, R.sub.1 denotes alkyl or cycloalkyl, R.sub.2 and R.sub.3 denote a hydrogen atom, alkyl or cycloalkyl. R.sub.4 denotes alkyl, cycloalkyl, arylalkyl, aryl, alkylaryl, alkylpolyoxyalkylene or a residue of polyhydricphenol. A is a residue of polynuclearpolyhydric phenol or hydrogenated derivative thereof of from 2 to 4 valent. n is 1 to 8. m is 1 to 5. L is 0, 1 or 2. X is a hydrogen atom or ##STR2##
