A procedure for the crystallization of a blend of polyethylene terephthalate and polyethylene isophthalate

摘要

The polyphenylene ester mixture of polyethylene ester and polyethylene isophenyl ester is coated with carbonated asphalt (such as ethylene carbonate or propylene carbonate) with fast crystallization speed and lower temperature than uncoated fur, This reduces the latency of the pelvis, which is added during the crystallization process, followed by solid polyurethane.
