Claims31
A chemical composition comprising:
- a polymeric particle having a core/shell structure, the core comprising an ultraviolet absorber;
- and
- fluoropolymer.
A multiphase polymeric composition comprising a polymeric core phase, a polymeric shell phase, and a fluoropolymer phase,
- wherein the polymeric core phase comprises an ultraviolet absorber, and
- wherein the polymeric core phase and the fluoropolymer phase do not substantially contact one another, but both the polymeric core phase and the fluoropolymer phase contact the polymeric shell phase.
A method of preparing a multiphase polymeric composition comprising a polymeric core phase, a polymeric shell phase, and a polymeric film-forming phase, wherein the polymeric core phase comprises an ultraviolet absorber, the composition being prepared according to steps comprising:
- powder coating onto a substrate polymeric materials comprising the polymeric core phase, the polymeric shell phase, and the polymeric film-forming phase, and fusing the polymeric materials to form a multiphase polymeric composition wherein the polymeric core phase and the polymeric film-forming phase do not substantially contact one another, but both the polymeric core phase and the polymeric film-forming phase contact the polymeric shell phase.
