Other compounds that may be used alone or in conjunction with the foregoing tin or silicon compounds include metal halides, metalloid halides, alkoxysilanes, imine-containing compounds, esters, ester-carboxylate metal complexes, alkyl ester carboxylate metal complexes, aldehydes or ketones, amides, isocyanates, isothiocyanates, imines, and epoxides.Īfter formation of the modified polymer cement or latex, the rubbery elastomer, the processing aid, and other optional additives such as oil, are isolated from the solvent and preferably dried. 5,332,810, which is incorporated herein by reference. Exemplary compounds include SnCl 4, R 2SnCl 2, and RSnCl 3, which are disclosed in U.S.
Preferably, R is a simple alkyl group having from 1 to about 10 carbon atoms. Useful compounds that may be used to couple or functionalize the tail end of the living polymers include, but are not limited to, those compounds that can be defined by the formula R nMX 4−n, where R is an organic group, M is silicon or tin, X is a halogen atom, and n is a numeral from 0 to 3. In yet another embodiment, anionically-polymerized elastomers, whether head-functionalized or not, are terminated with a coupling agent or a terminating agent that will impart an end functionality to the polymer.
