Starch-polyethylene blends

Headspace-GC-MS analysis is useful for the determination of volatile compounds in samples that are difficult to analyze by conventional chromatographic means, e.g., when the matrix is too complex or contains substances that seriously interfere with the analysis or even damage the column. Peak area for equilibrium headspace gas chromatography depends on, e.g., sample volume and the partition coefficient of the compound of interest between the gas phase and matrix. The need to include the partition coefficient and thus the sample matrix into the calibration procedure causes serious problems with certain sample types, for which no calibration sample can be prepared. These problems can, however, be handled with multiple headspace extraction (MHE) [118]. Headspace-GC-MS has been used for studying the volatile organic compounds in polymers [119]. The degradation products of starch/polyethylene blends [120] and PHB [121] have also been identified. [Pg.126]

These kinds of products are normally used in mulch films, bags and packing. Other systems have been investigated. The combination starch/ polyester has been claimed to be fully biodegradable (Tokiwa et al., 1993). Others are partially biodegradable, like starch/polyethylene/poly-e-caprolactone blends (Corp, 2001) and their derivatives or combinations of starch and modified polyesters. [Pg.133]

The use of mixtures of polymers where one of them acts as a compatibilizer between starch and less hydrophilic components e.g. PVA in TPS/polyethylene blends or a low molecular weight polymer like poly(ethylene glycol) in TPS/PLA blends [50, 110, 115, 119]). [Pg.333]
