✦ Synopsis

Abstract

Thiokol‐type polymers have been prepared by condensation of crude 2: 2′‐dichlorodicthyl sulphide with sodium polysulphides. More useful products are obtained by replacing part of the 2 : 2′‐dichlorodicthyl sulphide by the corresponding sulphoxide and condensation of the latter with ethylene dichloride under similar conditions also gives useful polymers.

The work described is mainly based on the use of sodium tetrasulphide condensates but concurrently and in conjunction, similar work mainly based on the use of sodium disulphide condensates was carried out by the Paint Research Station with the view to producing more resinous than rubber‐like polymers. The outcome of the work of the Paint Research Station is detailed in British Patents Nos. 573,308,573,333 and 576,721 (Jordan and Aiken) which also cover the use of the sulphoxide compound.

Polymer aerogels were prepared from 2,4-dihydroxybenzoic acid (DHBA) and formaldehyde (F) using synthesis mixtures containing up to 17% solids content and Fe, Cu or Ni introduced by ion exchange. Carbon aerogels were then obtained by carbonisation. The materials were characterised by TEM and N 2 ads
