ABSTRACT:
New hindered piperidinoalcohol 1,1,1-trioxyalkanes are disclosed. In the 1,1,1-trioxyalkanes, at least on 1,1,1-trioxyalkane group is linked to the residue of an alcohol linked to the 4-position of a 2,2,6,6-tetraalkylpiperidine compound having 12 to 75 carbon atoms. For each 1,1,1-trioxalkane group, there are 1 to 3 tetraalkylpiperidine groups. The alkyl groups linked to the piperidine ring have from one to five carbon atoms each. The fourth substituent on the carbon atom of the 1,1,1-trioxyalkane is a hydrogen atom or an aliphatic group having one to five carbon atoms.
The disclosed 1,1,1-trioxyalkanes protect a variety of synthetic resins against the deteriorative effects of exposure to actinic light.
Stabilizer compositions comprising a disclosed 1,1,1-trioxyalkane and a known polymer stabilizer, as well as synthetic resin compositions stabilized with such stabilizer compositions, are also disclosed.
