Patent number: 4252935Abstract: Esters of glycidyl polyethers of saturated phenols are especially useful in coating compositions having a low organic solvent content. The esters are the reaction products of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of phenols where the aromatic rings of the phenols are saturated.Type: GrantFiled: July 31, 1979Date of Patent: February 24, 1981Assignee: PPG Industries, Inc.Inventors: Carl C. Anderson, William J. Birkmeyer, Roger M. Christenson, Rostyslaw Dowbenko, Ronald J. Lewarchik

Patent number: 4224423Abstract: A method for the manufacture of an aminoformaldehyde resin. An amino compound is reacted with formaldehyde or paraformaldehyde in the liquid phase the latter being ensured by the presence of a reactive modifier in the reaction mixture. The reactive modifier comprises an amino-formaldehyde resin which is capable of reaction with further monomers and capable of rendering the mixture of reactants liquid at least at the temperature at which the reaction is to be carried out.Type: GrantFiled: June 2, 1978Date of Patent: September 23, 1980Assignee: British Industrial Plastics LimitedInventors: Dennis H. Ogden, George Inverarity

Patent number: 4220576Abstract: The process for the manufacture of a plaster product comprises adding a u-formol or melamine-formol resin to a calcium sulphate base powder, the starting powder being constituted by partially hydrated calcium sulphate (plaster alone or with gypsum, or anhydrite with gypsum such as phosphogypsum). The percentage of resin, measured in weight of dry extract of the latter with respect to the weight of the dry extract of the powder to which it is added, is comprised between 1 and 5%. A powder-resin-water mixture is formed by a process of extrusion. The product thus formed is heated to a temperature comprised between 105.degree. and 120.degree. C. Articles having exceptional surface hardness and durability can be formed therefrom by a continuous extrusion.Type: GrantFiled: July 25, 1978Date of Patent: September 2, 1980Assignee: Societe d'Investissement pour le Developpement des Appareils MenagersInventor: Francois Tatard
