Patent number: 4189416Abstract: Disclosed herein is a composition and method for sizing textiles which employs as the sizing agent a mixed salt comprising the reaction product of an interpolymer with a fixed alkali base and a fugitive alkali base; the latter subsequently being volatilized away during processing of the sized textile. The interpolymer comprises (a) 1.0 molar proportion of a maleic or fumaric acid or anhydride or partial ester, (b) from 0.1 to 3.0 molar proportion of a monovinylidene aromatic monomer and (c) from zero to a finite molar proportion of an alpha-olefin, a vinyl ester alpha-beta-ethylenically unsaturated nitrile, an acrylic or methacrylic ester or a vinyl alkyl ether. From 10 to 70% of the free carboxyl groups of the interpolymer are combined with fixed base, i.e., non-volatile amine or alkali metal base, and from 5 to 90% of said free carboxyl groups are combined with fugitive base, i.e., ammonia, ammonium hydroxide or volatile amine.Type: GrantFiled: April 5, 1973Date of Patent: February 19, 1980Assignee: Monsanto CompanyInventor: Charles R. Williams

Patent number: 3973055Abstract: The dielectric recording media comprise electroconductive substrates coated with dielectric resin binder. The process comprises dispersing an organophilic clay pigment in the dielectric resin binder and coating the electroconductive substrate with the dispersion. The organophilic clay pigment is obtained by treating calcined kaolin clay with an organotitanium compound.Type: GrantFiled: January 27, 1975Date of Patent: August 3, 1976Assignee: Monsanto CompanyInventors: Albert H. Markhart, David R. Cahill

Patent number: 3960485Abstract: Warp textile sizes comprising interpolymers of vinyl esters are recovered by extraction of the interpolymer from woven cloth with an aqueous solvent to form an aqueous solution of the interpolymer. The interpolymmer is precipitated from the aqueous solution by adjusting the alkali metal ion concentration of the solution within defined limits and adding acid to reduce the pH to the range of 1 to 3. The precipitated polymer is isolated from the supernatant solution and is reused by dissolving it in an aqueous base to yield a sizing solution.Type: GrantFiled: June 19, 1974Date of Patent: June 1, 1976Assignee: Monsanto CompanyInventors: Joel Fantl, Joseph G. Martins
-
