摘要:
This invention relates to an organosilicon compound having a cyclic structure with nitrogen atom and silicon atom, and one or more sulfur atoms in its molecule, and having a bonding side of one or more groups having as small steric hindrance to silicon atom, a rubber composition formed by compounding an inorganic filler (B) and the organosilicon compound (C) into a rubber component (A) consisting of natural rubber and/or diene-based synthetic rubber, and a tire using such a rubber composition.
摘要:
The invention provides a rubber composition prepared by mixing, per 100 parts by mass of the rubber component comprising at least 50% by mass of a diene-based rubber, from 20 to 150 parts by mass of a filler, and from 0.05 to 30 parts by mass of a compound A which has a specific amidine structure and has a functional group reactive with the diene-based rubber. The rubber composition improves both a high elastic modulus and a low tan δ. The invention also provides a pneumatic tire using the rubber composition.

摘要:
This invention relates to a novel compound capable of largely reducing hysteresis loss of a rubber composition but also highly improving wear resistance, and more particularly to an organosilicon compound characterized by having one or more silicon-oxygen bond (Si—O) and 1-10 sulfur atoms (S) in its molecule, including one or more chain alkoxy groups and having one or more nitrogen atoms (N) at a position distant by 3-8 atoms from silicon atom (Si).

Embodiments of the present disclosure are directed to functionalized copolymers produced by copolymerization of at least one conjugated diolefin monomer and at least one vinyl monomer, the functionalized copolymer including at least one functional group having silica reactive moieties, wherein the functionalized copolymer has a degree of hydrogenation of 75% to 98 mol % as measured using proton nuclear magnetic resonance spectroscopy (1H NMR). In one or more embodiments, the silane modifier may include an oxygen-containing moiety, wherein the oxygen atom of the oxygen-containing moiety may not be directly bonded with the silicon atom.
