ABSTRACT:
A new process for preparing a polyhydric alcohol 3-alkyl-thiopropionate polyolefin resin stabilizer is provided, in which there is heated a reaction mixture containing a polyhydric alcohol, an alpha-olefin having 6 to 40 carbon atoms, and betamercaptopropionic acid or a lower alkyl betamercaptopropionate in the presence of an organic peroxide or azonitrile reaction initiator, and the polyhydric alcohol 3-alkylthiopropionate polyolefin resin stabilizer is recovered from the mixture.
Polyolefin resin compositions stabilized with the stabilizer prepared by the process of this invention, and stabilizer compositions comprising the stabilizer prepared by the process of this invention together with a phenol and/or an alkaline earth metal salt of a monocarboxylic acid are also provided.
