摘要:
A process for producing polyester pellets is claimed. This process consists in a) grinding the melt of the polyester, after the production thereof, to a powder with particle sizes of d90,3=10 to 150 mm, and b) processing this powder to pellets with particle sizes of 150 to 1600 mm. The polyester pellets produced by this process are notable for improved solubility at low temperatures
