Abstract
Thermally stabilized resin compositions are provided which contain one or more cyclic iminoether compounds represented by formula (I), cyclic iminoester compounds represented by formula (II), or both and an amine thermal stabilizer, wherein X is as described herein, and A and B are each, independently, a single bond, substituted or unsubstituted alkylene selected from the group consisting of methylene, ethylene, propylene, butylene, 1-methylethylene, 1,1-dimethylethylene, 1,2-dimethylene, 1-ethylethylene, 1-1-diethylethylene, 1-propylethylene, 1-butylene, 1-hexylethylene, and 1-methyltrimethylene.
Claims7
A thermally stabilized resin composition comprising a resin which contains a thermally stabilizing effective amount of one or more cyclic iminoether compounds represented by formula (I) or a cyclic iminoester compound represented by formula (II) or both, and an amine thermal stabilizer:
- ##STR5## wherein, X is a single bond or a divalent organic group selected from C.sub.2 -C.sub.10 alkylene, arylene selected from the group consisting of phenylene, naphthalene, and biphenylene, cyclic alkylene selected from the group consisting of cyclohexylene and cyclohexanedimethylene and C.sub.2 -C.sub.10 alkylene containing a hetero atom,
- or X is a group of formula (III) ##STR6## wherein, R.sub.1 and R.sub.2, are each, independently, selected from the group consisting of hydrogen, methyl, ethyl, propyl, butyl, hexyl, octyl, decal, phenyl, tolyl, cyclohexyl, and benzyl,
- Y is a divalent organic group selected from the group consisting of ethylene, propylene, butylene, pentamethylene, hexamethylene, octamethylene, nonamethylene, decamethylene, phenylene, naphthalene and diphenylene or a group of formula (IV):
- ##STR7## wherein, Z is a member selected from the group consisting of --O--, --CO--, --S--, --SO2--, --CH.sub.2 --, --CH.sub.2 CH.sub.2 --, or --C(CH.sub.3).sub.2 --, cyclopentylene, cyclohexylene, methylene-phenylene and methylene-phenylenemethylene;
- and
- A and B are each, independently, a single bond, substituted or unsubstituted alkylene selected from the group consisting of methylene, ethylene, propylene, butylene, 1-methylethylene, 1,1-dimethylethylene, 1,2-dimethylene, 1-ethylethylene, 1,1-diethylethylene, 1-propylethylene, 1-butylene, 1-hexylethylene, and 1-methyltrimethylene;
- wherein said one or more of cyclic iminoether compounds of formula (I) or a cyclic iminoester compound of formula (II) or both are present in an amount of from 0.02 to 5.0 wt. % and said amine thermal stabilizer is present in an amount from 0.02 to 3.0 wt %.
