PRODUCING METHOD FOR POLYESTER
PROBLEM TO BE SOLVED: To produce a polyester, in which bubbles and a fish eye are difficult to be generated in moldings and crystallization controlling properties of the moldings are good and transparency is excellent and also dirt of a mold at time of molding is difficult to be generated. SOLUTION:...

| description | PROBLEM TO BE SOLVED: To produce a polyester, in which bubbles and a fish eye are difficult to be generated in moldings and crystallization controlling properties of the moldings are good and transparency is excellent and also dirt of a mold at time of molding is difficult to be generated. SOLUTION: In the method for producing a polyester, in which the polyester obtained by melt polymerization is discharged in a strand shape from a die head, cooled and solidified and thereafter cut into a chip state, the polyester is cut into the chip state in the conditions satisfying formula (1). 0.02 |
