Abstract
Polymer compositions for coating of metal surfaces including moieties that interact with a metal atom in the metal surface and optionally containing antifoulant moieties. These polymer compositions provide lubricious coatings for medical devices, anticorrosion coatings for metal components, and antifoulant coatings for marine components such as propellers. The polymer composition is synthesized in a safe manner in which the synthesis components are added to a synthesis vat and there is no need for filtration or removal of waste materials in any step including the consumer use. As such this invention provides an environmentally sound approach to composition synthesis, formulation development, and consumer use.
Claims19
A coating composition comprising a macromolecule comprising
- (a) a dimethylsiloxane unit;
- and
- (b) a substituted methylsiloxane unit of formula:
- [—Si(Me)(—R1—Y1—R2—Ar)—O—]
- wherein R1 is a C1 to C5 hydrocarbylene group;
- Y1 is —NH—C(O)—, —C(O)—NH—, —C(O)—O—, or —O—C(O)—;
- R2 is a nothing or a C1 to C5 hydrocarbylene group;
- and
- Ar is a heteroaryl group comprising at least one atom that comprises a lone electron pair.
A coating composition comprising
- (a) heterocyclic group comprising an atom that comprises a lone electron pair;
- (b) polyethylene;
- and
- (c) biologically active residue.
A method of preparing a coating composition comprising the step of reacting a polysiloxane that comprises an amino group, a carboxylic acid group, or a hydroxyl group, with a heteroaryl compound comprising an atom that comprises a lone electron pair, and that further comprises an amino group, a carboxylic acid group, or a hydroxyl group.
