Abstract
A process of producing a high molecular weight alkenylphenol polymer which comprises cationically polymerizing an alkenylphenol, such as vinylphenol, in the presence of a nitrile using a cationic polymerization initiator in a homogeneous reaction system. The resulting alkenylphenol polymer is useful as a starting material for preparing a thermosetting resin, a high molecular weight electrolytic substance, an ion exchange membrane, adhesives, glass-fiber-reinforced composite materials, etc.
Claims10
A process of producing an alkenylphenol polymer which comprises cationically polymerizing an alkenylphenol in the presence of a nitrile using a cationic polymerization initiator, wherein said nitrile is a saturated aliphatic mononitrile or an aromatic nitrile having a boiling point below about 200.degree. C. at 760 mm Hg and the concentration of the alkenylphenol monomer in said nitrile solution is from about 1 to about 50% based on the weight of said nitrile.
