ABSTRACT:
A polymer material formed from the reaction between ingredients comprising an azido polymer containing at least about 5 weight percent azido groups; and at least one multifunctional dipolarophile having reactive groups selected from an acrylic and an acetylenic ester or amide, the resulting polymer material comprising triazoline and/or triazole groups. Also, a method of improving the burn rate of an azido polymer including the steps of reacting an azido polymer with the above-described multifunctional dipolarophile.
