PRODUCTION OF POLY(ETHYLENE 2,6-NAPHTHALATE) |
摘要 |
Disclosed herein is a novel crystalline form of low molecular weight poly(ethylene 2,6-naphthalate). This crystalline form may be produced from molten or glassy low molecular weight poly(ethylene 2,6-naphthalate) material by means of rapid heat transfer to or from the material. The poly(ethylene 2,6naphthalate) composition is suitable for use as a starting material for solidstate polymerization in order to produce polymers of higher molecular weight. |
