| titleOfInvention | Particulate polymer materials |
| abstract | The present invention provides the use of a hollow particulate glass as a support for an active agent, characterised in that said hollow particulate glass is produced by pyrolysis of glass-coated polymer particles which are produced by copolymerising an unsaturated heterocyclic monomer and squaric acid, nwherein said polymer has the structure:n nwhere each R, which may be the same or different, is hydrogen or optionally substituted alkyl; the ring nitrogen atom of the heterocyclic ring is unsubstituted or alkyl (especially methyl) substituted; X is a bond or a bridging group (preferably a bond); y is zero or a positive integer (preferably zero); and z is a positive integer the value whereof determines the molecular weight of the polymer. |
