Abstract: The change of elastic modulus and tangent of angle of mechanical loss of materials based on polyvinyl butyral solutions in a mixture of monomers of di(1-methacryloyloxy-3-chloropropoxy-2-)methylphosphonate and 2-hydroxypropyl methacrylate has been investigated by the method of dynamic mechanical analysis. The presence of several peaks on the temperature dependences of tgd was observed, which is probably due to the presence of regions differing in crosslinking density. At 10 wt. % of polyvinylbutyral content in the process of (co)polymerization its partial migration to the surface of the formed polymeric material occurs.
