Polymer blends with nondegradable polymers

Table 5.10 Mechanical Properties of Blends of Polylactide with Nondegradable Polymers... 

Biodegradation studies of starch blends have not been conclusive where a nondegradable synthetic polymer has been the blend component probably biodisiategration would be a better term to describe these polymers. The principal deficiencies of products based on this chemistry, aside from the incomplete biodegradation, are water-sensitivity of manufactured articles, and the balance of this and biodegradation with the starch level ia the product. 

In recent years, environmentally degradable plastics (EDPs) have attracted growing attention because of their potential use in the replacement of traditional nondegradable plastic items deriving from fossil fuel feed stocks. In this connection, PVA has been widely utilized in specific mereological segments for the preparation of blends and composites with several natural, renewable polymers.
