    摘要： Novel polyether polyureides useful in the manufacture of plastics, sealants, molds, foams and coatings. The novel composition comprises a mono- or di-substituted ureido-terminated polyoxyalkylene prepared by reacting a primary amine-terminated polyoxyalkylene containing material with suitable substituted ureido forming compounds at temperatures in the range from about 20.degree. C to about 150.degree. C in a molar ratio of about one molecule of ureido forming material for each terminal primary amino group.

    摘要： 2. IN CURING A POLYETHER ACRYLATE WHICH CONTAINS AN NF2 GROUP ATTACHED TO EACH OF 2 TO 4 CARBON ATOMS IN RECURRING MONOMER UNITS AND WHICH IS USED AS A BLINDER IN A HIGH-ENGERGY SOLID ROCKET PROPELLANT, THE IMPROVEMENT WHICH COMPRISES CURING THE POLYETHER ACYLATE TO A STRONGER BINDER WITH AN ADMIXED PROPORTION OF 0.1 TO 4 WT. PERCENT OF A DIALKYL PEROXYCARBONATE HAVING 2 TO 4 CARBON ATOMS IN THE ALKYL GROUPS AS CURING ININIATOR, THE CURING BEING CARRIED OUT AT A TEMPERATURE IN THE RANGE OF ABOUT 20* TO 50*C. 4. IN CURING A POLYETHER ACRYLATE TO FORM A STRONGER BINDER AS SET FORTH IN CLAIM 2, SAID POLYETHER ACRYLATE BEING AN ACRYLATE OF POLY (BI(NF2) PENTENE-1 OXIDE) WITH 1 TO 3 TERMINAL ACRYLATE GROUPS, SAID POLYETHER ACRYLATE BEING MIXED WITH A LIQUID OXIDIZER CONTAINING NF2 GROUPS, A SOLID OXYGEN CONTAINING OXIDIZER, AND A METAL FUEL AS IT IS BEING CURED BY DIETHYL PEROXYCARBONATE AS A DIALKYL PEROXYCARBONATE CURING INITIATOR.
