    摘要： The invention provides a stabilizer for synthetic resins containing as an effective component a mixture comprising at least one phenolic type compound selected from those of formula (I),
    wherein m is an integer of 0 to 6 and R, represents a C 1 -C 3 alkyl group, and at least one sulfur-containing compound (II) selected from those of formula (11-1),
    wherein R 2 represents a C 4 -C 20 alkyl group, and those of formula (11-2),
    wherein R 3 represents a C 3 -C 18 alkyl group, and R 4 and R s are selected independently from a hydrogen atom and C 1 -C 6 alkyl groups. There is also provided a synthetic resin, e.g. a polyolefin and preferably polypropylene, incorporating a stabilizer of the invention.

    摘要： The invention provides phenolic type compounds represented by the general formula (I),
    wherein n represents an integer of 1 to 4, and the A's are selected from groups of the formula
    In which R, is a C 1 -C 3 alkyl group, a stabilizer for synthetic resins containing said compound as an active ingredient and stabilized synthetic resins containing said stabilizer. The invention also provides a stabilizer for synthetic resins containing as an active ingredient a mixture comprising at least one phenolic type compound as above and at least one sulfur-containing compound selected from those of formulae (II-I) and (11-2),
    wherein R 2 represents a C 4- C 20 alkyl group, and
    wherein R 3 represents a C 3 -C 18 alkyl group and R 4 and R 5 are selected independently from hydrogen atom and C 1 -C 6 alkyl groups. Synthetic resin, e.g. polyolefin and preferably polypropylene, may contain stabilizers according to the invention.
