[Study on the binary blends of poly(epsilon-caprolactone) with different cellulose derivatives by infrared spectra].
The interaction in binary blends of poly (epsilon-caprolactone) with nitrocellulose, ethyl cellulose, and cellulose carbamate was studied by FT-infrared spectroscopic technique. The results indicate that the self-hydrogen-bonding interaction in cellulose derivatives decreases obviously with the decrease of O-H groups in one structure unit, while the interaction between poly(epsilon-caprolactone) and cellulose derivatives is enhanced. The enhancement of such interaction affects the crystalliztion behavior of PCL evidently, and the crystallization ability of PCL in the blends weakens.
