Abstract
The material, which is usable for the production of biodegradable articles in film, sheet or fiber form, can be produced by extrusion from a molten mass including a synthetic thermoplastic polymer and a destructured starch to which a boron containing compound, such as boric acid, metaboric acid, borax and derivatives thereof has been added. Articles made of this material have improved transparency, Young's modulus and tear strength.
Claims20
A composition useful for the production of biodegradable films, sheets, and fibers obtained from a molten mass, said molten mass comprising a synthetic thermoplastic polymer, destructured starch, a high boiling point plasticizer, up to 40 weight percent water referred to the starch/water system, and a boron-containing compound.
