This patent application concerns the fabrication, composition and properties of new plastic materials containing two components, A and B; said A is a polymer obtained by synthesis from reagents derived from fossil sources, such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene-terephtalate, and other polymers containing functional groups such as COOH, OH, NH 2 , CONH, COOR, where R = alkyl or aryl, as for example in co-polyethylene-polyvinyl alcohol (PETPVA), co-polyesters, polylactons, polyamides, polyamines, polyacrylic acid and polyalcohols; said B is a mix of water soluble biopolymers obtained from residual biomass of urban, agriculture, agricultural-industrial, animal source, and/or from coal such as peat and lignite, or contains the sulphonated derivatives of the above soluble biopolymers, and/or the lignisulphonates isolated or produced from the effluents of the pulp and paper industry. |
