    Abstract: Biodegradable graft copolymers derived from a carbohydrate and at least one α,β-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying.

    Abstract: The invention relates to a method for making light-weight dimensionally stable wood-thermoplastic composite material composed of wood chips and a thermoplastic polycaprolactone. The manufacturing process of composite material comprising the steps of compounding virgin materials with single-screw extruder and production of uniform homogeneous plate-like composite with calendering apparatus. The calendering process comprises of several cycles, folding, cooling and reheating steps. During the gentle manufacturing process fragile wood chips maintain their 3-D structural properties in polymer matrix resulting light, mechanically strong wood-plastic composite.

    Abstract: A biodegradable thermoplastic polymer masterbatch composition comprising a blend of at least one biodegradable thermoplastic polymer containing high loading of a particulate filler uniformly dispersed therein. The amount of the biodegradable thermoplastic polymer is generally from about 25% to about 50% by weight and the amount of the filler is from about 75% to about 50% by weight, based upon the total amount of one biodegradable polymer and the at least one filler. The uniform dispersion of the fillers is desirably obtained by adding small particles of the filler to a melt of the biodegradable polymer and blending using high shear equipment with special screw geometry. The masterbatch composition is then physically blended with additional biodegradable thermoplastic polymer and extrusion processed into final articles such as blown and cast films, molded products, and the like. The masterbatch multi-stage approach of the present invention results in a product that has improved physical properties and lower costs over that of a one step blend of the same amount of a biodegradable thermoplastic polymer and a filler that is subsequently heat formed into a final product.
