Abstract
The radical telomerization of vinylidene fluoride (VF2) and of vinyl a cetate (VAc) with 2-hydroxyethylmercaptan, and the radical cotelomeriz ation of both monomers with the same thiol have been investigated. In each case, the chemical structures and the chain lengths have been det ermined by various methods in order to understand the reactivity and t he direction of addition of both monomers. This study indicates a grea ter reactivity for VAc relative to VF2 since a twofold excess of VAc m ay be introduced into the cotelomers for an equimolar initial feed con centration of the monomers. Of the telomers produced, it was noted tha t the diadduct is HOCH2CH2SCH2CF2CH2CH2OCOCH3, indicating that the thi yle radical reacts preferentially with VF2. This study is a preliminar y to obtaining curable VF2 oligomers.
