Abstract
A study was made of hydrophosphorylation of polyallene in the presence of organic peroxides. Hypophosphorous acid and its salts, alkylphophonous acids and dialkylphosphites were used as hydrophosphorylating agents. Phosphono-alkylated polymers containing up to 11% phosphorous, insoluble in organic solvents and not supporting combustion were obtained. It was found that hydrophosphorylation of polyallene reduces the crystallinity of polymers and increases their heat stability. Polymer-analogous conversions of polyallenephosphonous acid were carried out.
