Wenn wir in der folgenden Abhandlung von Oligomeren sprechen, dann meinen wir damit niedermolekulare Polymere bis zu einem Molekulargewicht von etwa 104, die sowohl einheitlich als auch uneinheitlich sein konnen. 

Poly(isobutylene) dicarboxylic acid was prepared by oxidation of the copolymer of isobutylene with a diene 53,54). The most efficient oxidizing agent was the system KMn04-periodic acid. Oxidation of a copolymer of isobutylene and 2,3-dimethyl-butadiene afforded a polymeric bis-ketone54). 

When benzoyl aryl tellurium and bis[benzonitrile]dichloropalladium were stirred in chloroform, polymeric bis[aryllellurolato]palladium compounds were isolated. The benzoyl group was cleaved from the tellurium atoms during these reactions. 

The polymeric bis[arcnetellurolato]platinum compounds were depolymerized by tri-phenylphosphane to mononuclear complexes1.

Benzophenone with tertiary amines has been used to polymerize bis 2-[2-(methacryloyloxy)ethoxy]ethyl phthtilate and triethylene glycol dimethacrylate in bulk, while mixtures of ZnO and l,8-diamino-3,6-diazaoctane have been used to emulsion-polymerize styrene. An internal keto-imine compound,...

A typical method for fabricating multiple complex layers is as follows. First, Au-S-AB-tpy SAM was prepared by immersing an Au/mica or Au/ITO plate in a chloroform solution of tpy-AB-SS-AB-tpy (37). In the case of connecting Fe11 ion, the tpy-terminated surface was immersed in Fe(BF4)2 (aq) or (NH4)2Fe(S04)2 (aq). The bis(tpy)iron structure was prepared by immersing the film with the metal-terminated surface in a chloroform solution of tpy-AB-tpy (38). The latter two processes were repeated for the preparation of multilayered (namely, polymeric) bis(tpy)iron(II) complex films (Figure 9.13). 

Phenyl sulfide, thianthrene, and phenyl disulfide had been formed at 41 C before appearance of the colored complex. The amount of each compound peaked at different times and temperatures. Phenyl sulfide in the first major compound formed but is soon displaced by thianthrene at temperatures above 90 C. The rather large amounts of thianthrene could even have been larger, however, as part of it crystallized from the samples and did not completely redissolve. Phenylthiothianthrene was the major heavy component, the heaviest to pass through the GLC column. Thiophenol, phenyl disulfide, and phenyl trisulfide were present in small amounts throughout most of the polymerization. Bis(phenylthio)benzene was formed in small amounts during the polymerization. This is a novel product of the reaction between benzene and sulfur with AlCl and was not detected among the products in Table 1. This compound can be converted easily into phenylthiothianthrene.

Copolymers containing phenylene units were prepared by electrochemically polymerizing bis(2-thienyl)ben-zenes [11,12]. 

Weitere Methoden, mit denen eine Naherungsrechnung ohne genauere Kenntnis des Gitterspektrums moglich ist, stammen von Thiriing (fiir hohe Temperaturen) und Houston (fur tiefere Temperaturen) [vgL z. B. Maradudin, Montroll, Weiss (1963)]. Sie haben jedoch auf Polymere bis-her keine Anwendung gefunden. 

Coordination of p-(l,3-butanedione)-A -phenylglycine with a variety of metal ions yielded a number of mixed chelate polymers [13] (53). This study is described in added detail under polymeric bis()8-diketonates) (Chapter IX).
