Polynitroalcohols (PNA) were obtained by A N ‐reaction of nitro oligomers from ground waste rubbers (NO‐GWR) with C 1 ‐C 2 ‐aldehydes in presence of organic bases triethanolamine, triethylamine and cyclopropylamine. The A N ‐reaction was studied at temperatures from 30 to 50°C, time 4 h, and NO‐GWR : aldehyde = 1 : 0.5/2.0 mass ratios in the solution. PNA were characterized by elemental analyses, such as 1 H NMR spectra, IR spectroscopy—baseline method with internal standard and thermal analyses. The quantitative functional composition of PNA (%NO 2 , %CO, and %OH groups) was proved to be similar to the composition of PNA obtained from model butadiene–styrene nitro oligomer (BSNO). It was concluded that NO‐GWR could replace NO based on elastomers in nitro aldol reaction with formaldehyde and acetaldehyde. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 3241–3250, 2006
