STABILIZATION OF METHYLMETHACRYLATE-BUTADIENE-STYRENE GRAFT COPOLYMERS AGAINST THERMAL OXIDATION |
| 摘要 |
The instant invention relates to a stabilized composition of methylmethacrylate-butadiene-styrene graft copolymers with selected sterical ly hindered phenolic antioxidants and thioethers. Further subjects of the invention are a process for the stabilization of methylmethacrylate-butadien e- styrene graft copolymers and the use of selected sterically hindered phenoli c antioxidants together with a thioether for the thermal stabilization of said graft copolymer.
