  • Patent number: 4331793
    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.

  • Patent number: 4299867
    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.
