DISPERSED CRYSTALLIZATION GERM, POLYMER COMPOSITION, ITS PRODUCTION METHOD AND MOLDED PRODUCT Russian patent published in 2023 - IPC C07F9/6574 C08J3/20 C08L23/00 C08K5/527 

FIELD: polymer materials.

SUBSTANCE: invention relates to methods for modification of polymer materials. A dispersed crystallization germ is proposed, containing a compound of the formula (1), where a content of phosphate ions in the dispersed crystallization germ is equal to or exceeds 5 ppm and equal to or less than 8000 ppm of the weight of the compound represented by the formula (1). A polymer composition for the production of molded products, containing the specified polymerization germ, a method for the production of a polymer composition, and a molded product obtained using a composition are also proposed.

EFFECT: use of the proposed dispersed polymerization germ allows for an increase in the reliability of its supply and improvement of a color tone of a molded product.
