Novel silicones having the general formula <CHEM> wherein Q is an aromatic nucleus, Z is -S- @-, <CHEM> or -O-, R is a bivalent group or a functional bivalent group, each R<1> is chosen from monovalent hydrocarbon radicals and functional hydrocarbon radicals and any one R<1> may be the same as or different from another R<1>, R<3> is hydrogen or a hydrocarbon radical or a functional group or atom, x is O or an integer of 1 or more, F is a functional group or atom, with the proviso that F is not primary amino when Z is other than -O-, and T is a group chosen from alkoxy, aryloxy or other substituted or unsubstituted oxyhydrocarbyl radical and a group having the general formula <CHEM> wherein Q, Z, R, R<1>, R<3> and F are as defined above and any one R may be the same as or different from the other R and one R @ may be different from the other R<3>. These compounds may be made by reacting the compound <CHEM> where G denotes alkoxy or aryloxy or other substituted or unsubstituted oxyhydrocarbyl radical under conditions set out in the specification. The compounds are suitable for making copolymers of silcones with other organic chemicals, curing catalysts for epoxies, urethane and the like. |
