Use of DMA-material pocket to determine the glass transition temperature of nitrocellulose blends in film form.

•Blends containing different ratios of polycaprolactone/nitrocellulose were prepared.•Films of pure polymers and blends were characterized by DMA – material pocket.•DMA – material pocket successfully reproduced Tg values of each pure polymer.•Tg of the blends were between the Tg of pure polymers, so they were very miscible.•Tg behavior of the blends was given by a decreasing logarithmic function.
