Abstract
The quasi-homogeneous (“synthesis in gel”) conditions for functionalization of polyvinyl chloride (PVC) with thiourea were experimentally selected. It was found that the best solvent for the formation of PVC gel is DMF, ensuring formation of the gel in the range of polymer concentrations from 10 to 30%. The composition of the products was characterized by elemental analysis data, the specific features of their structure were established by Fourier-transform IR spectroscopy and thermogravimetry. It was shown that thiourea reacted with PVC as an N-nucleophile to form thiocarbamoyl groups in the polymer structure. The maximum achieved total degree of functionalization was 0.31. The reaction was accompanied by cross-linking and partial dehydrochlorination.
