Abstract
Bis(3,4-dialkylbenzylidene) sorbitol acetals are provided for the formula: ##STR1## in which R.sub.1 and R.sub.2 are independently selected from lower alkyl groups containing 1-4 carbon atoms, or together form a carbocyclic ring containing up to 5 carbon atoms.
Claims4
Bis(3,4-dialkylbenzylidene)sorbitol acetals of the formula:
- ##STR16## in which R.sub.1 and R.sub.2 are independently selected from lower alkyl groups containing 1-4 carbon atoms which together form a carbocyclic ring containing up to 5 carbon atoms.
A polyolefin plastic composition having improved transparency and desirable taste and odor characteristics which comprises a polymer selected from aliphatic polyolefins and copolymers made from at least one aliphatic olefin and one or more ethyleneically unsaturated comonomers, said composition further containing at least one bis(3,4-dialkylbenzylidene)sorbitol acetal of the formula:
- ##STR17## in which R.sub.1 and R.sub.2 are independently selected from lower alkyl groups containing 1-4 carbon atoms which together form a carbocyclic ring containing up to 5 carbon atoms.
