POLYMER MATERIALS WITH REDUCED STICKINESS, METHOD OF OBTAINING SUCH MATERIALS AND CHEWING-GUM COMPOSITIONS CONTAINING SUCH MATERIALS Russian patent published in 2009 - IPC C08F279/02 A23G4/08 

FIELD: chemistry.

SUBSTANCE: proposed is a polymer material with low stickiness, which has a carbon-carbon polymer skeleton with a straight or branched chain and several side chains, joined to this skeleton, where the side chains directly bonded to carbon atoms of the polymer skeleton have formula (I) or formula (II) , where R¹ is H, -C(O)OR⁴ or -C(O)Q, and R² is -C(O)OR⁴ or -C(O)Q, under the condition that, at least one of R¹ and R² is a -C(O)Q group; R³ is H or -CH₃; R⁴ is H or an alkyl group with 1 to 6 carbon atoms; Q is a group with formula -O-(YO)_b-(ZO)_c-R⁵, where each of Y and Z independently represent an alkylene group, with 2 to 4 carbon atoms, and R5 is H or an alkyl group with 1 to 4 carbon atoms; a equals 3 or 4, and each of variables b and c independently equals 0 or an integer from 1 to 125, under the condition that, the sum b+c lies between 10 and 250, preferably from 10 to 120.

EFFECT: said polymer material can be substituted for part of a water-soluble gum base in a chewing-gum composition, thereby obtaining a composition with low adhesion to surfaces.
