Abstract
A resinous polymer containing the recurring unit <FORM:0896301/IV (a)/1> and terminal groups <FORM:0896301/IV (a)/2> where R1 and R2 are aromatic radicals and T is phenyl, halophenyl or hydroxyl, may be made by reacting a dihalosilane with either (a) a difunctional phenylene Grignard reagent or (b) a dihalobenzene and a suspension of a finely divided alkali metal in an inert solvent. In Examples, (1) diphenyldichlorosilane was added with stirring to a cooled (-80 DEG C.) suspension of p-phenylenedimagnesium dibromide in tetrahydrofuran and benzene, and the reaction mixture was allowed to warm to room temperature overnight. The reaction mixture was cooled in ice, hydrolyzed with aqueous HCl and extracted with ether to yield, when dried and freed of solvent, a tacky brown resin which when heated at 300 DEG C. (at 5 mm.) yielded a brittle brown fluorescent resin; (2) a similar product was obtained from the same reactants but using diethyl ether as the solvent; (3) p-dibromobenzene and diphenyldichlorosilane in xylene were added with stirring to a suspension of sodium in xylene containing iodine and the mixture was refluxed in an atmosphere of argon to yield, after separation by centrifuge and freeing of solvent, a brown resin. The preferred product of the invention is a thermoplastic resin which can be cured with benzoyl peroxide to a thermosetting resin.
