✦ Synopsis
Abstract
A number of oligomeric p‐phenylenesilanes containing 2‐6 silicon atoms per molecule and a series of low molecular weight poly‐p‐phenylenesilanes (n = 10‐30) have been prepared by Wurtz‐type condensation reactions involving appropriate combinations of p‐chlorophenyl‐ and chloro‐silanes. The polymeric products have been characterized by infrared spectroscopy, analytical and thermogravimetric data, and number‐average molecular weights, the low value of which is presumably caused by participation of the solvent (toluene) in the reaction. The polymers started to lose weight at temperatures varying from 310 to 485°.

## Abstract Linear organotin polymers with molecular weights (M~w~)in the range of 45 000 to 100 000 have been obtained by poly‐addition reactions involving organotin dihydrides and α,ω‐diynes, such as 1,5‐hexadiyne, 1,8‐nonadiyne, and 1,4‐diethynylbenzene. A number of 1‐stanna‐2,6‐cycloheptadiene
## Abstract It has been shown that di‐__p__‐styrenyl derivatives of germanium, tin, and lead as well as 1,4‐divinylbenzene and 3,9‐divinylspirobi(__meta__‐dioxan) react with diphenyltin dihydride to yield linear poly‐addition polymers containing tin or tin and germanium or lead in the main polymer
