PROBLEM TO BE SOLVED: To provide a mercaptosilane capable of exhibiting a high amplification ratio, a low hysteresis loss, and high abrasion resistance, even in a short mixing time economically allowable, with assured proessability, and simultaneously capable of realizing more decreased release of an alcohol when compared with a trimethoxy- or triethoxy-substituted melcaptosilane. SOLUTION: This mercaptosilane is expressed by general formula I [R 1 is an alkyl polyether -O-(R 5 O) m -R 6 ]. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a silane denatured filler of biopolymer, biooligomer oxide or silicate, which has an adequate coating more improved by rubber reactive silane on the surface, which has a dynamic property equivalent to that in a silane filler mixture produced in a well known rubber field and which has a dynamic property more improved than that in a silane filler mixture produced in a well known rubber field; and also to provide a filler of biopolymer, biooligomer, oxide or silane, which is silane denatured without performing a silane reaction in water or an organic solvent. SOLUTION: The silane denatured filler of biopolymer, biooligomer, oxide or silicate is obtained by reacting at least one of fillers of biopolymer, biooligomer, oxide or silicate with at least one silane in a compressed gas.

摘要:
PROBLEM TO BE SOLVED: To provide an organosilicon compound that is not able to release volatile alcohol during binding to a filler and at the same time retain a high reactivity with respect to the filler. SOLUTION: A method of producing the organosilicon compound expressed by general formula I comprises contact and reaction of a silane expressed by general formula II with an alcohol expressed by general formula R'-OH under the decomposition of R IV -OH. In this case the mole ratio of the R'-OH and R IV -OH is ≥1 and the R IV -OH is continuously or non-continuously separated from the reaction mixture. In the general formulas I, II, X is SH, SCN or their mixture, and R IV is a methyl or ethyl group. COPYRIGHT: (C)2005,JPO&NCIPI
