A study was made of the effect of polymerization temperature on the syndiotacticity of polyvinyl formate. Vinyl formate was polymerized with ultraviolet light initiation in the temperature range from −20 to +30°C. The value of (Ep — Et)/2 obtain

Polychloral diol, unlike polyoxymethylene diol, is not readily capped in the presence of alkali catalysts. Polychloral is capped under acid conditions by acid anhydrides and chlorides and does not appear to undergo degradation during the process. Evi

Although dichloroacetaldehyde has only one chlorine less than chloral, the polymerization and polymer characteristics are quite different. Dichloroacetaldehyde is readily polymerized by Lewis acid catalysts to polymer with terminal hydroxyl groups. T

Chloral was polymerized by means of cationic and anionic initiators and the products compared. Anionic catalysts readily produce high molecular weight polymer (DP ∼ 300–600), but a DP of only 200 could be produced with cationic catalysts. The ani
