Notes:
Polyvinylacetophenone was made by the Friedel-Crafts reaction of acetyl chloride or acetyl bromide on polystyrene, in carbon disulfide, using aluminum chloride. Similar reactions, using bromoacetyl bromide or chloroacetyl chloride, gave insoluble polyvinylphenacyl halides. A soluble, low-molecular-weight polyvinylphenacyl chloride was obtained using chloroacetyl chloride and monomeric styrene. Polyvinylphenacyl bromides of limited Solubility were obtained by direct bromination of polyvinylacetophenone. Vacuum pyrolysis of polyvinylacetophenone gave p-vinylacetophenone monomer in good yield. At atmospheric pressure, the product was about half p-vinylacetophenone and half p-ethylacetophenone. At intermediate pressure, an intermediate proportion was obtained.
