Novel monomers of the general formula ##STR1## where b is 0 or 1, a is 1, 2, 3 or 4, R.sup.2 is a monovalent alkyl radical and R is an organic radical. The novel monomers may be employed to produce novel copolymers useful as hydrogel, soft non-hydrogel and/or rigid gas permeable contact lens materials.

Vinyl carbonate and vinyl carbamate contact lens material monomers

Contact lenses are made from the polymerization product of a monomer mixture comprising a polybutadiene-based compound as represented by formula (I)

Polybutadiene-based compositions for contact lenses

Organosilicon-containing materials are useful in articles such as biomedical devices, including contact lenses.

Organosilicon-containing materials useful for biomedical devices

Polymeric materials comprising novel wetting agents such as 2-isopropenyl-4,4-dimethyl-2-oxazolin-5-one, 2-vinyl-4,4-dimethyl-2-oxazolin-5-one, and the like.

Hydrophilic oxygen permeable polymers

Organosilicon-containing materials are useful in articles such as biomedical devices, including contact lenses. The materials include macromonomers endcapped with at least one ethylenically unsaturated radical, and monomers. The macromonomers and monomers include units of the formula: ##STR1## wherein: each Y is --O-- or --NR.sup.30 -- wherein R.sup.30 is H or C.sub.1 -C.sub.6 alkyl;
