MATURATION OR RIPENING INHIBITOR RELEASE FROM POLYMER, FIBRE, FILM, SHEET OR PACKAGING Russian patent published in 2015 - IPC A01N25/10 A01N3/00 A01N3/02 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. A thermoplastic composition contains a thermoplastic polymer and a cyclodextrin-modified thermoplastic polymer, having an inclusion complex with cyclodextrin, covalently bonded with a thermoplastic polymer and containing a cyclodextrin part and an inhibitor having the structure where each of R¹, R², R³, R⁴ is independently hydrogen or a C_1-16-hydrocarbon group and where at least one of R¹ or R² is methyl. The thermoplastic polymer composition is intended to produce fibres, films, fabrics, soft packaging, hard containers, laminates, covers or inserts for storing agricultural products.

EFFECT: method of producing a cyclodextrin-modified thermoplastic polymer includes covalently bonding a cyclodextrin part with a polyolefin to form a grafted cyclodextrin composition and contacting the grafted cyclodextrin with an inhibitor, wherein contacting is performed in a closed space.
