Process for the preparation of a copolymer of 3,3-bis (azidomethyl) oxetane with glycidol

摘要

FIELD: chemistry.;SUBSTANCE: method of producing 3.3-bis (azidomethyl) oxetane copolymer with glycidol is described, where m = 60-90, n = 0.9-1.8, lies in the fact that at the first stage cationic polymerization of 3.3-bis (chloromethyl) oxetane with glycidol is carried out at a ratio of 1: (0.016-0.020) mol in toluene at a temperature of 20-30°C in the presence of boron trifluoride etherate catalyst in an amount of 5-10 wt %, followed by heating at a temperature of 50-60°C for 2 hours; at the end of the polymerization the product is placed in water, filtered and air dried; at the second stage azidation of oligomer 3.3-bis (chloromethyl) oxetane with glycidol is carried out in a dimethylformamide medium at a temperature of 105-110°C for 30-35 hours in the presence of tetraethylammonium chloride (1-2 wt %), afterwards the product is placed in water, allowed to stand for 30 minutes, dried in a baker at a temperature of 50-60°C.;EFFECT: obtaining a copolymer with high output.;2 ex
