Structure of chlorinated poly(vinyl chloride). III. Preparation of poly(vinyl chloride)‐β,β‐d₂ as a model for the study of the mechanism of chlorination and of the chlorinated poly(vinyl chloride) structure

A method for the preparation of poly(vinyl chloride)‐β,β‐ d 2 (PVC‐β,β‐ d 2 ) as a model for the investigation of the mechanism of chlorination and of the CPVC structure has been suggested. The conditions of preparation of deuterated intermediates of a multistage synthesis of vinyl chloride‐β,β‐ d 2 and of suspension‐polymerized PVC‐β,β‐ d 2 have been described including the mass balance. Malonic acid was used as the starting compound. Tacticity values of a sample of PVC‐β,β‐ d 2 and its infrared and NMR spectra are presented and compared with data already published.
