POLYMER COMPOSITION FOR PRODUCING LINOLEUM Russian patent published in 2016 - IPC C08L27/06 C08K3/26 C08K5/05 C08K5/06 C08K5/15 

FIELD: chemistry.

SUBSTANCE: invention relates to filled plasticised polyvinyl chloride compositions intended for production of linoleum used in industrial and civil construction. Polymer composition contains polyvinyl chloride, product carbonisation epoxydated soya oil, calcium carbonate, plasticiser "EDOS" and tricyclo carbonate propyl ether of polyoxypropylene triol. At that, composition contains product of carbonisation epoxidated soya oil with content of 16.7% cyclocarbonate groups and 2.5 wt %

of epoxy oxygen. Composition contains following component ratio, weight parts: polyvinyl chloride 100, product carbonisation epoxidated soya oil - 5-10, calcium carbonate - 190-200, plasticizer EDOS - 90-110, tricyclo carbonate propyl ether of polyoxypropylene triol - 1-2.

EFFECT: higher bonding strength between layers of linoleum during delamination by more than 35 %, reduced wear capacity of more than 15 %, and migration of volatile components of composition is reduced by more than 7 %.
