  • Publication number: 20160194424
    Abstract: Provided are monomers of formula (I), polymerizable compositions comprising the monomer of formula (I) optionally together with other co-polymerizable monomers and polymers obtained or obtainable from the polymerizable compositions, where the monomer of formula (I) is represented thus: Wherein —R1 is —H or alkyl; —Z— is -0-, —NH—, or —N(R)—, where —R is optionally substituted alkyl or aryl; -Ar1 and -Ar2 are each independently optionally substituted aryl; and —R2 is —H, or optionally substituted alkyl or aryl.
    Type: Application

    Applicant: Contamac Limited
    Inventors: Timothy Charles Higgs, Richard Alexander Young
  • Publication number: 20160002144
    Abstract: A monomer for a polymerisable composition is described, the monomer having the formula (I): wherein: —R1 is —H or alkyl; —Z— is —O—, —NH— or —NR—, where —R is optionally substituted alkyl or C5-10 aryl; —Ar1 and —Ar2 are each independently optionally substituted C5-10 aryl; —R2 is —H, or optionally substituted alkyl or C5-10 aryl; and x and y are each independently 1 to 4. Also described are polymers formed from the composition, and ophthalmic lens products.
