    摘要： The present invention relates to a biodegradable poly-ceramic based on biodegradable formulations for the manufacture of disposable containers of accelerated degradation. These containers have high hardness, high resistance to heat and temperature. Poly-ceramic biodegradable materials are useful for the elaboration of disposable products destined to contain solid food or biological residues of degradation, as well as cold or hot liquids, utensils destined to be discarded or disintegrated as natural nutrients since they are friendly to the environment.

    摘要： A water-soluble and/or water-swellable hybrid polymer comprising: (i) from 5 wt.-% to 95 wt.-% water-soluble and/or water-swellable polysaccharide polymer; (ii) from 5 wt.-% to 95 wt.-% synthetic polymer comprising: (a) from 40 mol-% to 99 mol-% of repeating units according to Formula (1) (b) from 0.01 mol-% to 5 mol-% crosslinking or branching units, wherein the crosslinking or branching units result from the incorporation of a monomer comprising at least two olefinically unsaturated double bonds; (c) from 0.99 mol-% to 59.99 mol-% of repeating neutral structural units; wherein components (i) and (ii) are polymerized by radical precipitation polymerization in a polar solvent.

    摘要： A method of forming a hybrid physically and chemically cross-linked double-network hydrogel with highly recoverable and mechanical properties in a single-pot synthesis is provided. The method comprises the steps of combining the hydrogel precursor reactants into a single pot. The hydrogel precursor reactants include water; a polysaccharide; a methacrylate monomer; an ultraviolet initiator; and a chemical crosslinker. Next the hydrogel precursor reactants are heated to a temperature higher than the melting point of the polysaccharide and this temperature is retained until the polysaccharide is in a sol state. Then the single-pot is cooled to a temperature lower than the gelation point of the polysaccharide and this temperature is retained to form a first network. Thereafter, photo-initiated polymerization of the methacrylate monomer occurs via the ultraviolet initiator to form the second network.
