In the context of this chapter, the use of thermoplastic starch in blends with thermoplastic resins is of the main interest. As shown in Table 16.11, several blends have been developed, e.g., with vinyl alcohol copolymers (EVAl), polyolefins, aliphatic polyesters such as poly-e-caprolactone (PCL) and its copolymers, or polymers of glycols (e.g., 1,4-butanediol) with succinic, sebacic, adipic, azelaic, decanoic or brassihc acids, PCL + PVC. Compatibilization is possible by amylose/EVAl V-type complexes, starch grafted polyesters, chain extenders like diisocyanates, epoxies, etc. [Bastioli et al., 1992, 1993]. [Pg.1153]

In practice, the techniques of blending, compositing and nano-reinforcement are often used together. Thermoplastic starch/poly(vinyl alcohol) (PVOH)/clay nanocomposites exhibited the intercalated and exfoliated structures [260]. Mont-morillonite (MMT) with three types of cation or modifier (Na", alkyl ammonium ion, and citric acid) was examined. The prepared nanocomposites with modified montmorillonite indicated a mechanical improvement in the properties, in comparison with pristine MMT. [Pg.147]

The thermal stability of thermoplastic starch (TPS) blends containing various amounts of poly(hydroxybutyrate) (PHB) were evaluated [48]. Comparing PHB and TPS (soluble starch, glycerol 25%), the last one showed stability up to approximatefy 200°C at 10% of weight loss, while PHB exhibited the same weight loss oidy at 310°C. For blends containing a certain amount of PHB, thermal stability remains to a certain degree. [Pg.79]

Ratto et al. (1999) has examined poly butylenes sueeinate adipate (PBSA) terpolymer/granular starch composites for blown films and showed they could produce good film tensile properties and control biodegradation with granular starch addition. Thermoplastic starch/cellulose fibre extrudates and injection moulded products were examined by Funke et al. (1998) and they showed a reduction in water adsorption with increasing fibre content. Work by Halley et al. (2001) examined the use of thermoplastic starch-polyester blends for use in mulch film applications noting excellent field performance and biodegradability for these materials.

Liao et al. [261] reported biodegradable nanocomposites prepared from poly(lactic acid) (PLA) or acrylic acid grafted poly(lactic acid) (PLA-g-AA), titanium tetraisopropylate, and starch. Arroyo et al. [262] reported that thermoplastic starch (TPS) and polylactic acid (PLA) were compounded with natural montmorillonite (MMT). The TPS can intercalate the clay structure and that the clay was preferentially located in the TPS phase or at the blend interface. This led to an improvement in tensile modulus and strength, but a reduction in fracture toughness. [Pg.147]

Further, the blends may contain biodegradable additives to enhance their disintegration and biodegradabUity in the environment. Examples of biodegradable additives include thermoplastic starch, microcrystalline cellulose, methyl cellulose, hydrox5rpropyl cellulose, PLA, poly(hydroxy butyrate), or poly(vinyl alcohol) (50).

Another approach to biodegradability is to blend a biodegradable natural polymer with a thermoplastic synthetic pol5nner. Blends of starch with PE or with poly(vinyl alcohol) have been commercialized as packaging materials (176), although they have mainly been used in niche markets. Early materials were rather poor because the encapsulating effect of the PE on the starch protected it from water access, and, even if the starch was biodegraded, the PE was left... [Pg.2136]
