NUCLEATING AGENTS, METHODS FOR THEIR PRODUCTION AND RELATED POLYMER COMPOSITIONS Russian patent published in 2023 - IPC C07C31/30 C07C29/70 C08F10/06 

FIELD: polymers.

SUBSTANCE: present invention relates to modifier-modified zinc monoglycerolate in the form of crystallite agglomerates. The crystallite size of the modified zinc monoglycerolate based on the average length of the coherent domain is less than 30 nm in the <100> direction (size along the <100> zone axis), and less than 60 nm in the <011> direction (size along the zone axis <100>), as determined from the Scherrer equation by X-ray powder diffraction; and the aspect ratio calculated from the <100>/<011> coherent domain lengths is less than 0.65. Modified zinc monoglycerolate is useful as a nucleating agent and is very effective at low loading levels in polymers such as polypropylene. The invention also relates to a method for producing monoglycerolate, to compositions comprising it, and to options for using zinc monoglycerolate.

EFFECT: providing a modified nucleating agent with improved structure-forming efficiency at low loads, polymer compositions containing a nucleating agent, and an associated method for producing a nucleating agent.
