Abstract:
A hydrolytically stable polymeric material comprising a hydrolytically stable dendrimer core and polyolefin branches prepared in accordance with a reiterative process comprising one or more repetitive steps of:(a) reacting a diaminoalkane with an acrylonitrile to form a cyanide-terminated reaction product,(b) hydrogenating the reaction product to obtain a first generation product (G1) amine terminated dendrimer,(c) reacting G1 with an acrylonitrile and hydrogenating to form a second-generation product (G2) amine terminated dendrimer,(d) reacting G1, or G2 or successive Gn, wherein n is greater than 2, with a functionalized polyolefin and(e) recovering the polymeric material having a hydrolytically stable dendrimer core and branches of polyolefin emanating from the outer shell of the dendrimer.
