A polyester resin composition containing 100 parts by mass of a polyester resin and 0.01 to 10 parts by mass of a 2-amino-1,3,5-triazine derivative of Formula [1]:
a polyester resin molded body obtained by the composition, and a crystal nucleating agent including the triazine derivative. A polyester resin composition containing a crystal nucleating agent that makes it possible to produce, with high productivity, a polyester resin molded product that promotes polyester resin crystallization and maintains high transparency after crystallization and is applicable for a wide variety of uses can be provided.

Condensation products of melamine and phenylphophonic acid, a process for their preparation, their compositions with polymeric materials and their use as flame retardants in polymer substrates are provided. The compositions are especially useful for the manufacture of flame retardant compounds based on polyfunctional epoxides or polycondensates, such as polyesters, polyamides and polycarbonates.
It is an object of the present invention is to provide a polylactic acid resin composition in which a crystal nucleator appropriate for accelerating crystallization of polylactic acid rein is added.
