Abstract

PURPOSE: To obtain a polyester useful for injection molding, having improved crystallization rate, obtained by blending the polyester with a relatively small amount of finely divided nucleating agent for crystallization.
CONSTITUTION: A polyester obtained from an acid component consisting essentially of an aromatic dicarboxylic acid (preferably terephthalic acid) or its ester-forming derivative and a glycol component consisting essentially of an alkylene glycol (preferably ethylene glycol, etc.) or its ester-forming derivative is blended with 0.1W 0.5wt% dispersible nucleating agent (e.g., talc, etc.) for crystallization having an average particle diameter ≤0.8μ, preferably ≤0.5μ. The nucleating agent is added preferably before the completion of polymerization reaction with respect to the improvement of dispersibility.
