Claims17
A composition comprising the reaction product of:
- A) an ethylenically unsaturated compound having at least one group with the following structure or a salt thereof:
- and
- B) an ethylenically unsaturated composition having at least one urethane group.
A polyurethane material which releases salicylic acid by hydrolysis.
A method of producing a polyurethane material comprising
- 1) mixing:
- A) an ethylenically unsaturated compound having at least one group with the following structure or a salt thereof:
- and
- B) an ethylenically unsaturated compound having at least one urethane group;
- and
- 2) exposing the mixture to actinic radiation.
A composition comprising the reaction product of:
- A) an ethylenically unsaturated compound having at least one group with the following structure:
- and
- B) an ethylenically unsaturated compound,
- wherein the composition is capable of reducing the formation of microbial biofilm.
A method for modulating biofilm growth on a substrate, comprising coating said substrate with a composition comprising the reaction product of:
- A) an ethylenically unsaturated compound having at least one group with the following structure:
- and
- B) an ethylenically unsaturated compound.
A polymeric composition capable of reducing the formation of microbial biofilmon a substrate, the polymeric composition comprising at least one hydroxyl-containing bioactive agent incorporated in a non-biodegradable polymer backbone, wherein the bioactive agent is released hydrolytically upon exposure to aqueous conditions.
