FIELD: chemistry.
SUBSTANCE: invention relates to modified filler, including filler, which contains adsorbed on it triazole, which has the following formulae:
or 
,
where Zb represents alkylene C1-C4-group, where b equals 0 or 1; X represents H, NH2, SH, NHNH2, CHO, COOR, COOH, CONR2, CN, CH3, OH, NDD' or CF3; Y represents H or NH2; A is functional group, which represents SkR, SSO3H, SO2NRR', SO2SR, SNRR', SNQ, SO2NQ, S-(1,4-pyperazinediyl)-SR, 2-(1,3-dithianyl) or 2-(1,3-dithiolanyl); where R and R', which are similar or different, represent hydrogen, branched or non-branched C1-C12-alkyl, alkenyl, alkinyl; aryl; heteroaryl; alkylaryl; arylalkyl; arylene; heteroarylene or alkylarylene; k equals integer number from 1 to 8, if R represents H, with k equal 2-8 in other cases; Q represents (CH2)w, (CH2)xO(CH2)z, (CH2)xNR(CH2)z or (CH2)xS(CH2)z, where x equals 1-6, z equals 1-6 and w equals 2-6; E represents group Sw, where w equals 2-8, SSO, SSO2, SOSO2, SO2SO2; and said triazole can be, but not obligatorily, N-substituted with NDD'-substituent, where D and D', which are similar or different, represent H or C1-C4alkyl. Invention also relates to modified filler, including filler, containing triazole, bound to it, to elastomer composition, which contains modified filler, and to industrial product.
EFFECT: increase of elastomer composition wear resistance, improvement of hysteresis in elastomer composition and increase of elastomer composition wear resistance and reduction of hysteresis.
