Abstract
Abstract A stabilizer composition for a polymer is described, said composition comprising a chemically combined structure of the formula <IMAGE> wherein R is a group having the formula <IMAGE> wherein R1, R2, R3 and R4 are independently a hydrogen atom, or an alkyl or substituted alkyl group having 1 to 18 carbon atoms, with the proviso that at least one of R1 and R2 contains adjacent to the group HC- a carbonyl group which forms a part of an acid group, ester group, acid halide group, ketone group or aldehyde group; and X is -S(CH2)y-COOR5 or -S(CH2)y-OCOR5, wherein y is 1 or 2, or -SR5, -OCOR5 or -OCOCH=CHCOOR5, R5 being an alkyl or substituted alkyl group having 1 to 18 carbon atoms.

A stabilizer composition for a polymer, said composition comprising a chemically combined structure of the formula ##STR9## wherein R is a group having the formula ##STR10## wherein R 1 , R 2 , R 3 , and R 4 are independently a hydrogen atom, or an alkyl or substituted alkyl group having 1 to 18 carbon atoms, with the proviso that at least one of R 1 and R 2 contains adjacent to the group HC-- a carbonyl group which forms a part of an acid group, ester group, acid halide group, ketone group, or aldehyde group; and X is --S(CH 2 ) y --COOR 5 or --S(CH 2 ) y --OCOR 5 , wherein y is 1 or 2, or --SR 5 , --OCOR 5 or --OCOCH═CHOOR 5 , R 5 being an alkyl or substituted alkyl group having 1 to 18 carbon atoms.
Claim 2
Dependent Claim
145 words
A stabilizer composition for a polymer, said composition comprising a chemically combined structure of the formula ##STR9## wherein R is a group having the formula ##STR10## wherein R 1 , R 2 , R 3 , and R 4 are independently a hydrogen atom, or an alkyl or substituted alkyl group having 1 to 18 carbon atoms, with the proviso that at least one of R 1 and R 2 contains adjacent to the group HC-- a carbonyl group which forms a part of an acid group, ester group, acid halide group, ketone group, or aldehyde group; and X is --S(CH 2 ) y --COOR 5 or --S(CH 2 ) y --OCOR 5 , wherein y is 1 or 2, or --SR 5 , --OCOR 5 or --OCOCH═CHOOR 5 , R 5 being an alkyl or substituted alkyl group having 1 to 18 carbon atoms.
Claim 3
Dependent Claim
211 words
A stabilizer composition for a polymer, said composition comprising a chemically combined structure of the formula ##STR11## wherein R is a group having the formula ##STR12## wherein R 1 , R 2 , R 3 , and R 4 are independently a hydrogen atom, or an alkyl or substituted alkyl group having 1 to 18 carbons atoms, with the proviso that at least one of R 1 and R 2 contains adjacent to the group HC-- a carbonyl group which forms a part of an acid group, ester group, acid halide group, ketone group, or aldehyde group; and X is --S(CH 2 ) y --COOR 5 or --S(CH 2 ) y --OCOR 5 , wherein y is 1 or 2, or --SR 5 , --OCOR 5 or --OCOCH═CHCOOR 5 , R 5 being an alkyl or substituted alkyl group having 1 to 18 carbon atoms, wherein said composition is prepared by reacting an organotin halide having the formula ##STR13## wherein m+n=4 and m is 1 or 2, and R 1 , R 2 , R 3 , and R 4 have the same meaning as above; simultaneously with a reactant for substituting a sulfur atom for halogen and a reactant for substituting X for halogen, wherein X is as defined above.
Claim 4
Dependent Claim
211 words
A stabilizer composition for a polymer, said composition comprising a chemically combined structure of the formula ##STR11## wherein R is a group having the formula ##STR12## wherein R 1 , R 2 , R 3 , and R 4 are independently a hydrogen atom, or an alkyl or substituted alkyl group having 1 to 18 carbons atoms, with the proviso that at least one of R 1 and R 2 contains adjacent to the group HC-- a carbonyl group which forms a part of an acid group, ester group, acid halide group, ketone group, or aldehyde group; and X is --S(CH 2 ) y --COOR 5 or --S(CH 2 ) y --OCOR 5 , wherein y is 1 or 2, or --SR 5 , --OCOR 5 or --OCOCH═CHCOOR 5 , R 5 being an alkyl or substituted alkyl group having 1 to 18 carbon atoms, wherein said composition is prepared by reacting an organotin halide having the formula ##STR13## wherein m+n=4 and m is 1 or 2, and R 1 , R 2 , R 3 , and R 4 have the same meaning as above; simultaneously with a reactant for substituting a sulfur atom for halogen and a reactant for substituting X for halogen, wherein X is as defined above.
