POLYETHYLENE TEREPHTHALATE COMPOSITIONS AND METHODS OF USING THEREOF |
| 摘要 |
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 blowmoulding and foam extrusion.
