| Number | Title | Issue Date |
| 4219382 | Cationic fortified rosin size An acid-fortified rosin is reacted with a water-soluble polyalkylenepolyamine. The product is a modified rosin polyamidopolyamine. The product can be partially or completely neutralized with a rosin, thereby forming a rosin soap of the polyamidopolyamine.... | 08/26/1980 |
| 4207142 | Paper sizing agents A sizing agent for use in paper-making comprises an aqueous emulsion of at least one compound of the formula ##STR1## wherein x is an integer from 5 to 16 inclusive. The sizing agent can be used for either internal of surface sizing; and is effective... | 06/10/1980 |
| 4113506 | Emulsions of resinic acid isocyanates as sizing agents for paper Stable aqueous emulsions comprising a resinic acid isocyanate, a non-ionic and/or anionic emulsifier and an optionally chlorinated hydrocarbon are used as sizing agents for paper or paper-like materials.... | 09/12/1978 |
| 4071375 | Process for preparing stable aqueous dispersions of rosin-base material A process for preparing a stable aqueous dispersion of rosin-base material by dissolving in a water-immiscible organic solvent a rosin-base material composed of 0 to 95 wt. % of rosin and 100 to 5 wt. % of an adduct of rosin and ,ଲ-unsaturate... | 01/31/1978 |
| 4030970 | Surface sizing of paper with an acrylic copolymer where scum formation is minimized A process for surface sizing paper with a surface sizing composition, which comprises a copolymer of acrylic or methacrylic ester, alkali metal salts of acrylic or methacrylic acid, and acrylic or methacrylic acid, or ammonium or lower alkyl amine salts t... | 06/21/1977 |
| 4019921 | Chemical condensation products, their preparation and use Condensation products are formed from the unsaponifiable constituents of tall oil and alpha- beta- unsaturated mono- or poly-basic aliphatic acids or their derivatives. The condensation products can be formed into aqueous soap solutions in which form they... | 04/26/1977 |
| 3990939 | Paper sized with ketene dimer modified water-dispersible thermosettable cationic resins Disclosed are novel water-insoluble, water-dispersible thermosettable cationic resins derived by reaction of a water-soluble aminopolyamide, a hydrophobizing compound such as a ketene dimer and an epihalohydrin such as epichlorohydrin. The thermosettable ... | 11/09/1976 |
| 3966654 | Stable rosin dispersions Disclosed are essentially stable aqueous dispersions of fortified rosin which consist essentially of fortified rosin in finely-divided form; a water-soluble cationic resin, a specific example of which is a water-soluble cationic aminopolyamide--epichloroh... | 06/29/1976 |
