| titleOfInvention | Procedures for preparing rubber compositions and articles made from them |
| abstract | A process for preparing a rubber composition comprising: a) providing a mixture of: (i) at least one thiocarboxyl functional hydrolysable silane containing (1) a terminal thiocarboxyl group having a linear chain alkyl dispersing group attached to the atom carbon of the thiocarboxyl group and (2) a terminal silyl group having at least one hydrolysable alkoxy group directly attached to the silicon atom of the silyl group and (3) a bridge alkylene group that binds the thiocarboxyl group to the silyl group and having the general formula (R1O) 3-a (CH3) aSi-R2SC (> = O) R3 (1) in which: each presence of R1 is independently an alkyl group containing from 2 to 4 carbon atoms; R2 is a divalent alkylene group containing from 1 to 10 carbon atoms; R3 is an alkyl group containing from 5 to 9 carbon atoms; and a is from 0 to 2, in the amount of 0.2 to 20 percent by weight, based on the total weight of the rubber composition; (ii) at least one rubber containing carbon-carbon double bonds that includes or is a diene-based elastomer or rubber in the amount of at least 30 percent by weight, based on the total weight of the rubber composition, wherein said rubber (ii) is selected from the group consisting of styrene / butadiene rubber in solution, styrene / butadiene rubber in emulsion, polybutadiene, styrene-butadiene / acrylonitrile rubber derived from emulsion polymerization from 2 to 40 percent by weight of bonded acrylonitrile, styrene-butadiene rubber prepared by polymerization in organic solution functionalized with silane, 1,4-polybutadiene rubber prepared by polymerization in organic solution functionalized with silane and styrene-butadiene rubber coupled to tin; (iii) at least one reactive load with silane in the amount of at least 2 percent by weight, based on the total weight of the rubber composition, (iv) at least one activating agent, wherein said activating agent (iv) it is at least one guanidine-containing base of the general formula: R4R5N-C (> = NR6) -NR7R8 in which each presence of R4, R5, R6, R7 and R8 is independently hydrogen or a monovalent hydrocarbyl selected from the group consisting in alkyl, aryl, aralkyl and arenyl containing from 1 to 10 carbon atoms in the amount of 0.2 to 5 percent by weight, based on the total weight of the rubber composition, and (v) water, wherein said water (v) is added in an amount of 2 to 6 percent by weight to the reactive load with silane (iii) to form a reactive load with hydrated silane, wherein the amount is based on the total weight of the reactive load with hydrated silane, and the amount of water, based on the total weight of the rubber composition, varies from 0.1 to 1 5 percent by weight; b) subject the mixture provided in step (a) to reactive mechanical working conditions in the substantial absence of vulcanizing agent or agents; c) adding at least one vulcanizing agent (vi) in the amount of 0.2 to 5 weight percent, based on the total weight of the rubber composition, to the composition of step (b); d) mixing the composition of step (c) under non-reactive mechanical working conditions of 5 ° C to 130 ° C and a residence time of 0.5 to 30 minutes; and e) optionally, curing the rubber composition of step (d) at a temperature of 130 ° C to 200 ° C for a time of 1 to 60 minutes. |
