Example 1

A monomer according to the formula:

is made as described below.

3-(2-propionamidoethyl)-5,5'-dimethyl hydantoin is made as follows. A mixture of 128 grams ("g") (1 mole) of 5,5'-dimethylhydantoin and 99 g (1 mole) of 2-ethyl oxazoline is placed in a 1 liter ("L") round- bottom flask equipped with a condenser. The mixture is heated with stirring to 130°C and maintained at this temperature for 6.5 hours. The product is isolated by recrystallization from a mixture of ethylacetate and methanol (60/40 weight ratio).

3-(2-monohydrochloride aminoethyl)-5,5'-dimethyl hydantoin is made as follows. A mixture of 110 g (0.485 mole) of 3-(2- propionamidoethyl)-5,5'-dimethyl hydantoin, 81.0 milliliters ("m") of concentrated HCI and 250 ml_ of water is placed in a 1L round-bottom flask equipped with a condenser. The contents of the flask are heated with stirring to reflux temperature, and maintained at reflux for 12 hours.

The contents are then concentrated using rotavap under reduced pressure to remove the propionic acid. The resulting concentrate is added to 100 mL of methanol. The white crystals formed are filtered and dried.

3-(2-aminoethyl)-5,5-dimethyl hydantoin is made as follows. A mixture of 61.7 g ( 0.297 mole) of 3-(2-monohydrochloride aminoethyl)- 5,5'-dimethyl hydantoin, 24.8 g (25% solution, 0.3 mole) of NaOH, and 52 g of water are stirred at room temperature for 10 minutes. The water is removed using a rotavap under reduced pressure. The resulting free amine is dissolved in methanol (200 mL) to precipitate NaCI. The methanol is then removed under reduced pressure.

A mixture of 17.1 g (0.1 mole) of free amine prepared as above, 10.1 g of triethylamine (0.1 mole) and 100 mL of dichloromethane are taken in a 3-neck round-bottom flask equipped with a condenser and stirring means. The contents of the flask are cooled to 20°C and 10.45 g of methcryloyl chloride (0.1 mole) is added dropwise with stirring over a period of 60 minutes. The contents are stirred at room temperature for 16 hours. 10 mg of 4-methoxyphenol is added the and the contents are concentrated. To the concentrate is added 250 mL of acetone and the NaCI is filtered. The filtrate is then concentrated under reduced pressure to obtain the 3-(methacrylamidoethyl)-5,5'-dimethyl hydantoin monomer.

15 maintained at this temperature for 8 hours and are then cooled to room temperature. 3-(2-aminoethyl)-5,5-dimethyl hydantoin is made as described in Example 1 (17.1 g in 30 ml_ of methanol) and added over a period of 10 minutes. The contents are then heated to 7O 0 C with stirring and are maintained at this temperature for 4 hours. The methanol is then

20 distilled under reduced pressure to obtain a viscous product. 41.0 g of water is added to obtain a clear solution. Example 4

sparging and stirring the contents of the flask are heated to 62°C. 0.12 g of Vazo 56 initiator in 5.0 ml_ of water is added over a period of 25 min. After three hours, a second initiator portion (0.04 g Vazo 56 initiator in 2 mL water) is added in one shot. Then after 2 hours, a third initiator portion (0.04g Vazo 56 initiator in 1 mL water) is added in one shot and the reaction temperature is increased to 68 0 C. Stirring is continued for 3 hours and the mixture is then cooled to room temperature.

After 30 minutes, 25 mL of water is added for good stirring. After 4 hours, a second initiator portion (0.04 g Vazo 56 initiator in 2 mL water) is added in one shot. Then after 2 hours a third initiator portion (0.04g Vazo 56 initiator in 1 mL water) is added in one shot and the reaction temperature is increased to 70 0 C. Stirring is continued for 3 hours and the mixture is then cooled to room temperature.
