ADDITIVE FOR THERMOPLASTIC, ITS APPLICATION AND METHOD OF ITS PRODUCTION, METHOD OF PRODUCING THERMOPLASTIC, CONTAINING SAID ADDITIVE, AND THERMOPLASTIC, PRODUCED IN SAID WAY Russian patent published in 2008 - IPC C08K3/16 C08K5/98 C08L23/18 B29C49/04 C08K5/92 C08L23/20 C08L23/24 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of obtaining additives for thermoplastic materials, ensuring their controlled decomposition and giving them very light colour, and can be applied in processing thermoplastics by inflation extrusion in order to obtain film, extruding and moulding. Method of obtaining additive includes bringing salt of metal, including iron (III), in reaction with C₈-C₂₄ fatty acid or its derivative obtaining fat-soluble metal compound in process, in which appropriate oxidiser ensures preservation of all metal in final product. In addition, invention relates to additive, as such, to method of production of modified thermoplastics, containing said additive, as well as to modified thermoplastic materials.

EFFECT: ensuring stability of products from said thermoplastics during period of their usage and obtaining ability to decompose them soon after their utilization.
