1-10. (canceled)
A method comprising;
- use of a particulate polymer material as a support for an active agent, wherein said particulate polymer material is produced by copolymerising an unsaturated heterocyclic monomer and an acid selected from the group consisting of squaric acid. croconic acid and derivatives thereof.
A method comprising;
- use of a hollow particulate glass as a support for an active agent, wherein said hollow particulate glass is produced by pyrolysis of a glass-coated polymer produced by copolymerising an unsaturated heterocyclic monomer and an acid selected from the group consisting of squaric acid, croconic acid and derivatives thereof.
A particulate composition comprising;
- substrate particles containing an active agent, wherein said substrate particles are particles of a polymer produced by copolymerising an unsaturated heterocyclic monomer and an acid selected from the group consisting of squaric acid, croconic acid and derivatives thereof, wherein said substrate particles are coated with agents selected from the group consisting of a glass-forming coating and a glass-forming coating that is pyrolysed.
The composition of claim 19, wherein said matrix-forming material is selected from the group consisting of paint, varnish, lacquer, cement and concrete base.
