FIELD: chemistry.
SUBSTANCE: invention relates to spheroidal particles of polyester polymer and products made from the said particles. The particles are characterised by inherent viscosity It.V of at least 0.72 dl/g and/or at least two pressure peaks, and/or low degree of crystallinity in an interval of at least 20% and maximum degree of crystallinity Tcmax, and optionally but preferably contain 10 parts/million or less residual acetaldehyde. The spheroidal particles are dried, molten and objects are moulded from the molten mass.
EFFECT: provision for minimal degree of aggregation of particles in the drier.
