Abstract

The behavior of the readily available cis‐ (1) and trans‐ (2) 4, 5‐epoxy‐2‐pentenals toward classical cationic, anionic, and free radical initiators has been examined. Only the cationic polymerization of 1 gave soluble polymer of moderate molecular weights. This polymer possessed predominantly the cyclopolymerized furanose structure 12. Cationic initiation of 2 and anionic initiation of both 1 and 2 gave only crosslinked materials, and free radical initiators with 1 and 2 gave no polymer.

The decompositions of the following poly(vinyl chloride) models were investigated in the gas phase: trans-l,3-dichloro-l-pentene (in the range 310-380°), trans-5-chloro-3-heptene (296-357°), cis-4-chloro-2-pentene (295-340 °) and racem, and meso 2,4-dichloropentane at 351 and 370 °. The decompositio
