Abstract: A POLYETHER DIISOCYANATE HAVING THE FORMULA

OCN(RO)NRNCO

IN WHICH AT LEAST 60 PERCENT OF SAID R RADICALS ARE TETRAMETHYLENE, THE REMAINDER BEING ANOTHER ALKYLENE RADICAL HAVING FROM 2 TO 6 CARBON ATOMS AND N IS AN INTEGER FROM ABOUT 3 TO ABOUT 3000. THESE POLYETHER DIISOCYANATES MAY BE USED IN CHAIN EXTENSION AND CURING REACTIONS WITH COREACTANTS CONTAINING ACTIVE HYDROGEN, AND ELASTOMERS HAVING HIGH TENSILE STRENGHT AND ELONGATION CAN BE PRODUCED.

Abstract: 1,134,132. Coatings. MINNESOTA MINING & MFG. CO. 23 Feb., 1966 [14 Oct., 1965], No. 802S/66. Headings B2E and B2K. [Also in Division C3] Materials such as leather, concrete, wood, metals, plastics, rubbers, and textiles may be coated or treated with polishes, paints, coatings and finishes containing vulcanizates comprising polyether polyprimary polyamine/ epoxy resin formulations. The resins may be applied with or without filler materials, e.g. silica, carbon talc and titanium dioxide. The polyether polyamine has a molecular weight of at least 3500 and is prepared by the interaction of tetrahydrofuran and up to 40 mol percent of another cationically polymerizable cyclic ether or thioether in the presence of trifluoromethane-sulphonic anhydride at from - 40 to 80‹C in a polymerization system which is relatively free of monoalkylatable chain terminating agents and reacting the resultant dicationically active polyether with ammonia. Coatings applied on various substrates, including poly (chlorotrifluoroethylene) plastic, an elastomeric copolymer of chlorotrifluoroethylene and vinylidene fluoride and an elastomeric copolymer of vinylidene fluoride and hexafluoropropane, adhered tenaciously, especially after curing at 121‹C.

Abstract: BLOCK COPOLYMERS ARE PREPARED BY POLYMERIZING A CATIONICALLY POLYMERIZABLE MONOMER WITH POLYCATIONICALLY POLYMER OF A TETRAHYDROFURAN. IN AN EXAMPLE, 10 ML. OF TETRAHYDROFURAN AND 0.5 ML. OF TRIFLUOROMETHANE SULFONIC ANHYDRIDE WERE REACTED AT ROOM TEMPERATURE TO PRODUCE A DICATIONICALLY ACTIVE POLYTETRAHYDROFURAN. ETHYLENE OXIDE WAS POLYMERIZED ONTO THE ENDS OF THE TETRAHYDROFURAN POLYMER AT ROOM TEMPERATURE, AND THE BLOCK COPOLYMER PRODUCT THEN WAS QUENCHED IN DILUTE AQUEOUS SODIUM HYDROXIDE FOR 70 HOURS AND WAS WASHED WITH WATER CONTAINING SODIUM BROMIDE.
