Vinylidene chloride physical properties

Vinylidene chloride is a clear mobile liquid which is highly inflammable and with the following physical properties ... 

The connectivity indices therefore have different values for many polymers which have the same value of N. They thus enable distinctions to be made between polymers which have equal values of N but different structures, and different physical and chemical properties. Some examples of such polymers include polyisobutylene, polybutadiene, polyacrylonitrile, poly(vinylidene chloride) and poly(dimethyl siloxane), all of which have N=4. 

Property data from the literature (1-55,100,109-118) are given in Table 6-1. Since results for vinylidene chloride are not available in the DIPPR project, critical constants for vinylidene chloride were selected from Yaws (44,47). Critical constants for the remaining compounds were selected from the DIPPR project (5). Additional property data such as acentric factor, enthalpy of formation, lower explosion limit in air and solubility in water are also available. The DIPPR (Design Institute for Physical Property Research) project (5) and recent data compilations by Yaws and co-workers (44-55) were consulted extensively in preparing the tabulation.

The earliest preparation of CMS was based on the decomposition of a Saran co-polymer (90/10 mixture of vinylidene chloride and vinyl chloride) today CMS with a wide range of physical properties are made from a variety of natural and synthetic precursors. These include coal, coconut shell, phenol-formaldehyde resin, polyfurfuryl-alcohol, polyacrylonitrile, polyvinyl-alcohol, and cellulose, with coal tar pitch used in most cases as a binder [30-33],...

Copolymers afford a vast range of macroscopic properties that depend intimately on the composition of the material. NMR methods allow an analysis of the details of the composition, as is shown elsewhere in this volume, and also provide a view at the molecular level of the effects of copolymer composition on physical properties. Thus, the ethylene-propylene copolymers constitute a family of materials in which the physical properties depend partly on the over-all proportions of the monomers and partly on the arrangement of the two monomers within the. polymer [id]. Similarly, in copolymers of vinyl chloride and vinylidene chloride, a range of molecular motions is exhibited, depending upon composition. Fig. 11 shows how the temperature of the Tj-minimum and the magnitude of...
