ABSTRACT:
New ortho-alkylhydroxybenzyl substituted propanediol compounds of carboxylic acids, aldehydes, ketones, phosphites, phosphates, and phosphonates are disclosed. The propanediol compounds have in the molecule from one to four preferably from one to three ortho-alkylhydroxybenzylpropanediol units, each of which carries one to two ortho-alkylhydroxybenzyl groups, and are highly effective stabilizers for a variety of synthetic resins.
Stabilizer compositions comprising a orthoalkylhydroxybenzylpropanediol compound and a known polymer stabilizer, as well as synthetic resins stabilized with such stabilizer compositions, are also disclosed.
