Abstract
The present invention relates to rubber compositions containing an elastomer and a trivalent phosphorous compound-silica complex.
Claims16
A method of processing a rubber composition which comprises mixing
- (i) 100 parts by weight of at least one elastomer;
- with
- (ii) 1 to 150 phr of a trivalert phosphorous compound-silica complex;
- wherein said trivalent phosphorous compound is a compound of the formula (I) or (II):
- wherein each R1 is independently selected from the group consisting of hydrogen, alkls, having from 1 to 18 carbon atoms, and aryls and arylalkyls having 6 to 15 carbon atoms;
- and
- wherein each R2 is independently selected from the group consisting of halogens, alkys having from 1 to 18 carbon atoms, aryls and arylalkyls having form 6 to 10 carbon atom;
- amino alkylamino having from 1 to 10 carbon atoms, sulfur and alkylmercaptans.
