    Abstract: NOVEL N-3-OXOHYDROCARBON - SUBSTITUTED ACRYLAMIDES CONTAINING AN AROMATIC RADICAL IN EITHER THE 1 OR 3 POSITION ON THE OXOHYDROCARBON SUBSTITUENT ARE PREPARED BY THE REACTION OF ACRYLONITRILE WITH AN AROMATIC KETONE HAVING AT LEAST ONE ALPHA HYDROGEN ATOM, OR WITH A MIX, TURE OF SUCH A KETONE WITH AN AROMATIC OR ALIPHATIC ALDEHYDE OR KETONE HAVING AT LEAST ONE ALPLHA HYDROGEN ATOM, IN THE PRESENCE OF SULFURIC ACID; OR BY THE REACTION OF ACRYLONITRILE WITH A B=HYDROXY OXOHYDROCARBON OR AN A,B-UNSATRUATED OXOHYDROCARBON DERIVED FROM SAID AROMATIC KETONE OR MIXTURE. OIL-SOLUBLE PLOLYMERS FORMED BY THE POLYMERIZATION OF THESE ACRYLAMIDES, AND ALSO BY THE POLYMERIZATION OF ACRYLAMIDES CONTAINING AT LEAST TWO AROMATIC SUBSTITUENTS, ONE IN THE 1 POSITION AND ONE IN THE 3 POSITION OF THE NITROGEN SUBSTITUENT, ARE USEFUL AS VISCOSITY INDEX IMPROVERS FOR LUBRICATING OILS.

    Abstract: N- 3 -OXOHYDROCARBON-SUBSTITUTED 3-ALKOXYPROPIONAMIDES ARE PREPARED BY REACTING AN ALCOHOL WITH AN N-3OXOHYDROCARBON-SUBSTITUTED ACRYLAMIDE IN THE PRESENCE OF A STRONGLY ALKALINE CATALYST, THE MOLE RATIO OF ALCOHOL TO SUBSTITUTED ACRYLAMIDE BEING BETWEEN ABOUT 8:1 AND 12:1. THE PRODUCTS ARE USEFUL AS CHEMICAL INTERMEDIATES FOR THE PREPARATION OF NOVEL AND USEFUL COMPOUNDS; FOR EXAMPLE, N-(1-1-DIMETHYL-3-OXOBUTYL)-3-METHOXYPROPIONAMIDE CAN BE CONVERTED TO N-(1,1-DIMETHYL-3-HYDROXYBUTYL)-ACRYLAMIDE BY HYDROGENATION FOLLOWED BY ALKALINE PYROLYSIS.
