Moulding composition of polyethylene terephthalate reacted with a copolymer of maleic anhydride. |
| 摘要 |
<p>This invention relates to polyethylene terephtalate compositions comprising a reaction product of a PET resin and 0.05 to 5.0 WT % of a copolymer of maleic anhydride, optionally together with pyromellitic dianhydride. These compositions have improved melt strengths, which allow to apply them especially for extrusion blow-moulding and foam extrusion.</p> |
