  • (Meth)acrylic and (meth)acrylamide monomers, polymerizable compositions, and polymers obtained
    Patent number: 7498394
    Abstract: The present invention provides novel (meth)acrylic and (meth)acrylamide monomers and polymers produced from those monomers. The monomers of the invention each include only a single vinyl functionality and at least one non-vinyl functionality that can be varied to achieve desired monomer/polymer properties. The invention additionally provides methods of producing polymers from these mono-vinyl monomers.
    Type: Grant
