Abstract: A method is disclosed for separating alpha-1-proteinase inhibitor from a blood plasma fraction particularly from the Cohn fractionation scheme. An aqueous solution of the blood plasma fraction is held at a pH of about 6.5-8.5, and a temperature of about 2.degree.-50.degree. C. for a period of about 0.2-24 hours and then mixed with a poly-condensed polyglycol. The mixture may be held at a temperature of about 2.degree.-10.degree. C. for a period of about 1-24 hours. Next, the pH of the mixture is adjusted to selectively precipitate unwanted proteins from the solution of alpha-1-proteinase inhibitor which is separated from the solution and purified further. The amount of poly-condensed polyglycol and the pH of the mixture are selected accordingly.

Abstract: Resin-forming polyepoxides are mixed with polyoxazolidinyl compounds or polymers containing pendant oxazolidinyl groups in which the carbon atom in the 2-position of the heterocyclic ring is substituted with saturated hydrocarbon groups, such as dialkyl, or with an alkylene group forming a saturated ring with the carbon atom in the 2-position of the oxazolidinyl ring to form, in the absence of water, a stable composition which can be stored in closed containers for months without undergoing gelation. When such compositions are spread into films and the films exposed to moisture at ambient temperature, e.g., to ambient air having a relative humidity of at least 20% and temperature of about 15.degree. to 25.degree. C., the polymer serves to react with and cure the polyepoxide.

Abstract: The present invention is concerned with, as a hydrocurable composition, a mixture of an oxazolidine-functional polymer and a compound of a monomeric or polymeric character having a plurality of acryloxy groups. The first-mentioned polymer contains a plurality of pendant groups containing 2,2,-dialkyl oxazolidine groups. The mixture of these two components can be stored under anhydrous conditions in a closed container without co-reaction so that a one-pot or one-package composition can be made up with many conventional ingredients of coating compositions other than aqueous components and stored without gelling until the time for application when the composition may be applied at ambient temperature and humidity whereupon reaction between the main two components mentioned above occurs in the film deposited and the film set up.
