Stabilizer for polyolefin resin |
| abstract |
A new process for preparing a polyhydric alcohol 3-alkylthiopropionate polyolefin resin stabilizer is provided, comprising the steps of heating at 40 DEG -160 DEG C. an alpha-olefin having 6 to 28 carbon atoms with betamercaptopropionic acid or a lower alkyl betamercaptopropionate in the presence of an organic peroxide or azonitrile reaction initiator, esterifying the resulting 3-alkylthiopropionic acid or ester with pentaerythritol or tris(2-hydroxyethyl) cyanurate, and recovering the polyhydric alcohol 3-alkylthiopropionate polyolefin resin stabilizer 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. |
