Claims
- 1. A polymerisable monomer of structure ##STR26## wherein R.sub.1 and R.sub.2 are alkylene groups containing 2 or 3 carbon atoms, the same or different; one of A or B is a C.sub.2 -C.sub.18 alkyl group substituted by at least one hydroxy group and the other is a methacryloxy C.sub.2 -C.sub.18 alkyl group the alkyl portion being optionally substituted by a hydroxy group; and X=H, C.sub.1-18 alkyl or ##STR27## the said monomer being substantially free from non-polymerisable water-soluble contaminants.
- 2. A polymerisable monomer according to claim 1, wherein group A or group B is a substituted propyl group of structure ##STR28## wherein the substituent R.sub.3 is (meth)acryloxy.
- 3. A polymerisable monomer according to claim 1, wherein B=(meth)acryloxyhydroxypropyl.
- 4. A polymerisable monomer according to claim 1, wherein R.sub.1 =R.sub.2 =ethylene, X=H, A=hydroxybutyl and B=(meth)acryloxyhydroxypropyl.
- 5. A polymerisable monomer according to claim 1, wherein R.sub.1 =R.sub.2 =ethylene, X=H, A=dihydroxypropyl and B=methacryloxyhydroxypropyl.
