Organosilicon compounds which are particularly used as coupling agent, the compositions of elastomers (s) of the container and the articles by elastomers (s) prepared on the basis of such compositions

摘要

Organosilicon compounds having a silicon-bonded hydroxy or hydrolyzable group and a rubber-reactive aminopolysulfide group (I) are new. Organosilicon compounds having a silicon-bonded hydroxy or hydrolyzable group and a rubber-reactive aminopolysulfide group of formula (I) are new. R1 = an (un)saturated aliphatic and/or (un)saturated or aromatic (poly)carbocyclic hydrocarbon group optionally substituted or interrupted with O and/or NR or NRR'; R, R' = H or (un)saturated aliphatic and/or (un)saturated or aromatic (poly)carbocyclic hydrocarbon groups; x = 2-4; and R2, R3 = H or (un)saturated aliphatic and/or (un)saturated or aromatic (poly)carbocyclic hydrocarbon groups, but not both H, or NR2R3 is a 5- to 7-membered ring with 3-6 C atoms, at least one N atom and 0-2 double bonds. Independent claims are also included for: (1) five processes for preparing specific compounds (I); (2) diene elastomer compositions containing a white reinforcing filler, prepared using an organosilicon compound containing a group of formula (I); (3) production of the compositions of (2) by mixing the non-vulcanizing ingredients in an internal mixer at 80-200 deg C, transferring the mixture to an external mixer and adding vulcanizing agents and/or accelerators at a temperature below 120 deg C; (4) articles made from the compositions.
