Abstract: New chroman derivs. are of formula (I), where R = opt. substd. 6-20C aryl or aryloxy, 1-20C alkoxy, CN, COOR , COOH or CONH2; R = 8-30C C-organic residue; R = 1-20C alkyl, opt. with in-chain ether O atoms. Also claimed are; (i) a process for the prodn. of (I); (ii) stabiliser mixts. contg. cpd(s). (I) and an organic phosphite and/or phosphonite and/or amine; and (iii) organic material, esp. plastics, stabilised against the effects of light, oxygen and heat with 0.005-5 wt% (I) or the above stabiliser mixts.
