  • Polypyrrolidone alloys
    Patent number: 4243777
    Abstract: Intimate alloys of polypyrrolidone and hydrophobic linear polyesters and polyamides and processes for preparing such alloys. The intimate alloys comprise a major portion of polypyrrolidone and a minor amount of certain hydrophobic linear polymer additive and are characterized by improved fiber-textile properties. The intimate alloys are prepared by coprecipitation or by polymerizing polypyrrolidone from a mixture containing 2-pyrrolidone, alkaline catalyst and finely divided polymer additive.

  • 2-Pyrrolidone production
    Patent number: 4181662
    Abstract: A process for production of 2-pyrrolidone which comprises (a) contacting succinonitrile with water at a temperature between 150.degree. and 300.degree. C. and a pressure between 50 and 10,000 psig to thereby hydrolyze succinonitrile and (b) contacting the hydrolyzed succinonitrile with hydrogen in the presence of a heterogeneous hydrogenation catalyst and at a temperature between 200.degree. and 300.degree. C. and a pressure between 100 and 10,000 psig to thereby obtain 2-pyrrolidone.
