Novel poly(silylenealkynes), poly(silylenemethylenes), and poly(silylenephenylenes) with a regular alternating structure in the polymer backbone have been prepared by reductive coupling of special substituted silyl triflates or chlorides with potassium - graphite or by ring-opening polymerization of 1,3-disilacyclobutanes. The functionalization of these polymers with trifluoromethanesulfonic acid and following reactions with grignard reagents, amines, or lithium tetrahydridoaluminate gave novel polymeric derivatives. The protodesilylation reaction could be controlled by using different leaving groups (phenyl-, p-tolyl-, or p-anisyl-groups). In this way, the regular structure of the polymer backbone could be kept during the funtionalization reactions. Novel network-polymers have been obtained by intermolecular hydrosilylation reactions of the modified polymer derivatives. The polymers were characterized by NMR spectroscopy (29Si, 13C, 1H).
