    Abstract: A PROCESS FOR PRODUCING A POLYMER WATER-IN OIL EMULSION Described herein is a semi-continuous process for producing a polymer water-in-oil emulsion which process comprises: (a) combining: (i) an aqueous solution comprising at least one water-soluble monomer and (ii) a mixture comprising a hydrophobic liquid, a hydrophobic monomer and an oil-soluble surfactant; (b) homogenizing the mixture from (a) to form a water-in-oil emulsion; (c) deoxygenating said homogenized water-in-oil emulsion; (d) continually adding the homogenized water-in-oil emulsion to a reactor while adding thereto a deoxygenated initiator solution; (e) heating the mixture from (d) under polymerization conditions so as to form a polymer water-in-oil emulsion; and (f) recovering a polymer water-in-oil emulsion.

    Abstract: HIGH-ORTHO PHENOL-FORMALDEHYDE RESOLES CONTAINING HEMIFORMAL GROUPS Disclosed ore high-ortho phenol-formaldehyde resoles having stable hemiformal groups. These resoles are of low viscosity, are essentially free of unbound water and volatile organic compounds. They are curable to phenolic formaldehyde resinous solids and are particularly suitable for use in liquid injection molding processes to form composites.
