Book Description
The synthesis and characterization are described of linear polymers, having a carbon chain regularly interrupted by the Group IV elements silicon, germanium, tin or lead. Such polymers were obtained by means of: (1) poly-addition reactions involving an organotin dihydride and either a dienic, a diynic or a monoynic compound; (2) Wurtz-type poly-condensations involving appropriate combinations of p-chlorophenyl and chloro derivatives of the Group IV elements. The synthesis and polymerization of vinyl-type IVth group organometallic monomers is dealt with briefly. Furthermore, interesting IVth group metal-containing heterocyoles were prepared and also a few polymers, containing in addition to Group IV atoms other hetero-elements in their backbone. All polymer-forming reactions have been studied by carrying out model reactions on a low-molecular weight level. (Author).

Such polymers were obtained by means of: (1) poly- addition reactions involving an organotin dihydride and either a dienic, a diynic, or a monoynic compound; (2) Wurtz-type poly-condensations involving appropriate combinations of p-chlorophyenyl and chloro derivatives of the Group IV elements. The synthesis and polymerization of vinyl-type Group IV organometallic monomers is dealt with briefly. Furthermore, interesting Group IV metal-containing heterocycles were prepared and also a few polymers containing, in addition to Group IV atoms, other, other heteroelements in their backbone. All polymer-forming reactions were studied by carrying out model reactions on a low-molecular weight level.

Book Description
It was shown that di-p-styrenyl derivatives of germanium, tin, and lead as well as 1,4-divinylbenzene and 3,9-divinylspirobi (meta-dioxane) react with diphenyltin dihydride to yield linear poly-addition polymers containing tin or tin and germanium or lead in the main polymer chain. The polmeric products were characterized by infrared spectroscopy, analytical data and molecular weights, the latter varying from 14.000 for the lead-containing polymer to 110.000 for the 1,4-divinylbenzene adduct. Reactions of triphenyltin hydride and diphenyltin dihydride with mono- and di-p-styrenyl derivatives of germanium, tin, and lead yielding monomeric compounds containing two and three hydrocarbon-linked metal atoms were carried out as well.

Book Description
Linear organotin polymers with molecular weights in the range of 45000 to 100000 were obtained by poly-addition reactions involving organotin dihydrides and alpha, omega-diynes, such as hexadiyne-1,5, nonadiyne-1,8, and 1,4-diethynylbenzene. A number of 1-stannacycloheptadiene-2,6 derivatives (cyclic monomers derived from hexadiyne-1,5) were isolated. (Author).

Book Description
The results of a synthetic program directed towards the preparation of IVth main group organometallic polymers are presented. The main body of the report is concerned with the synthesis of linear polymers having a carbon chain regularly interrupted by tin (and in some cases other IVth group) atoms Such polymers have been obtained by means of true poly-addition reactions (hydrogen transfer polymerization) involving an organotin dihydride and either a dienic or a diynic or a monoyni C coumpound The synthesis of lVth group organometal-substituted polystyrenes carbon chain polymers containing the organometallic moiety as a substituent group as well as of a series of poly-p-phenylenesilanes-polymers consisting of chains of p-phenylene groups connected by dialkyl(aryl) silane groups are dealt with briefly.

Book Description
This volume is exclusively devoted to tetramethyllead. Owing to the recent large-scale use as an antiknock agent, its application, toxicological, biological, and environmental aspects are given much attention besides its chemical and physical properties. - Literature coverage up to 1986.
