2-CYANOETHYL ACRYLATE

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A cyanoethylacrylate/acrylic acid copolymer is prepared by mixing cyanoethylacrylate and acrylic acid in a molar ratio of 0.5 at a total solids concentration of 25 percent in cyclohexanone. The reaction solution also contains 0.04 percent 2,2'-azobis(isobutyronitrile) which acts as a free radical chain reaction initiator. As the reaction solution is heated, the 2,2'-azobis(isobutyronitrile) decomposes, with the evolution of nitrogen, forming two free radicals which initiate the polymerization of the cyanoethylacrylate and acrylic acid. The reaction solution is held at a temperature of 90° to 100° C. for 24 hours to form an oligomer of cyanoethylacrylate and acrylic acid having the following structure ##STR3## wherein x is such that the molecular weight is sufficiently low so that the oligomer remains soluble in cyclohexanone. As the reaction solution is heated forming two free radicals which

Procedure: A nitrogen line was connected to a two-necked flask (100 ml) provided with a cooling tube so that the air in the flask was replaced with nitrogen gas. 0.02 mole of cyanoethyl vinyl ether, which was distilled at least twice, 0.02 mole of cyanoethyl acrylate, 20 ml of acetone and 2,2'-azobisisobutyronitrile in an amount of 2mol% relative to the total amount of the monomers were then placed in the flask, followed by polymerization at 50° C. for 24 hours. The thus-formed copolymer was then reprecipitated by using methanol to obtain 4 g of an intended cyanoethyl vinyl ether-cyanoethyl acrylate copolymer. The composition ratio (cyanoethyl vinyl ether:cyanoethyl acrylate) of the copolymer was 2:3. A nitrogen line was connected to a two-necked flask (100 ml) provided with a cooling tube so that the air in the flask followed by polymerization at 50° C. for 24 hours The thus-formed copolymer was then reprecipitated

Procedure: The procedure of Example I was followed with 3.48 g of β-cyanoethyl methacrylate (commercially available from Union Carbide Corp., New York, New York) instead of β-cyanoethyl acrylate.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 7.11 g of acrylamide, 3.13 g of β-cyanoethyl acrylate (commercially available from Monomer-Polymer, Borden Chemical Co., New York, New York, under the designation #7437) and 0.01 g of 2,2'-azobis-[2-methylpropionitrile] catalyst were dissolved in 80 ml of dimethylformamide. This solution was polymerized under N2 in a sealed tube at 65° C. for 12 hours. A white viscous solution resulted which produced a precipitate in acetone. The precipitate was collected and dried under vacuum at 50° C. for 12 hours to yield a water-soluble white powder.
