We synthesized two reactive quaternary ammonium methacrylate compounds (QAC-10 and QAC-12) bearing a hydrophobic tail with different alkyl chain length. Cross-linked films with excellent antimicrobial property were obtained from a mixture of a polyurethane acrylate prepolymer and a reactive QAC via one-step UV curing. The QAC-containing films showed total kill against both Gram-negative Escherichia

Novel photosensitive compositions based on azlactone derived polymers are described. The polymers have a hydrocarbyl backbone and pendant peptide groups with free-radically polymerizable functionality attached thereto, said polymer further comprising at least one oxyacid group or salt thereof, and optionally quaternary ammonium salt groups. A high speed durable printing plate having a mild pH aqueous developability is disclosed which incorporates these polymers in combination with a photoinitiator. The polymers are also useful as proofing films in graphic arts applications.

A POSS modified polyacrylate fluorine-free waterproofing agent includes following components: 1-10 wt % of a functionalized POSS monomer, 2-20 wt % of methyl methacrylate, 3-26 wt % of butyl acrylate, 1-10 wt % of a long-chain acrylate monomer, 0.5-3.5 wt % of an initiator, 0.5-4 wt % of a reactive cationic emulsifier, and 50-80 wt % of deionized water. A method of preparing a POSS modified polyacrylate fluorine-free waterproofing agent is also disclosed.
