Description
| - Native or pre-gelatinized wheat starches (A and B types) or acetylated derivatives of native starch with degree of substitution DS of 1.5 - 2.3 (10, 20, and 40 % m/m) were blended with poly-(epsilon-caprolactone) (PCL). Structure of the prepared films was analysed by FT-IR spectroscopy in comparing with the initial polymers. The following mechanical characteristics of the prepared films were derived from the stress-strain curves: Young modulus, yield stress, tensile strength, and strain at break. Water absorption of PCL/starch (60/40) films was determined according to ISO 62. The films containing native and pre-gelatinized starch degraded in compost totally during the 1-2 months. Acetylation of starch molecules in the blends reduced the degradation rate. Chemical changes in the compost used for film exposition were measured.
