Process for producing a hydrophobic composite bioelastomer, comprising a cross-linked bioelastomer matrix in which an organic phase is dispersed, comprising the reaction of cross-linking of a hydroxyl-terminated polysiloxane with a silane coupling agent, comprising an acetoxysilane, to obtain a cross-linked polysiloxane with release of acetic acid. The reaction of cross-linking is carried out in the presence of starch to cause at least partial in situ acetylation by the acetic acid released from said starch that is incorporated in the cross-linked bioelastomer matrix.

Methods for the production of a biodegradable plastics material obtained from plant waste materials are provided which include the steps of dissolving plant waste material in an anhydrous solvent which includes anhydrous trifluoroacetic acid in order to dissolve a cellulose fraction of the material, the waste material being at least partly dehydrated in such a way that its water content is not likely to cause hydrolysis of the cellulose fraction, and removing the solvent from the solution containing the non-hydrolyzed cellulose fraction.

Process for the production of a polymer foam with use of hydrogel pearls as porosity generating template, comprising the steps of:&#x2014;providing a matrix of polymer or prepolymer in viscous state including, as a dispersed phase, hydrogel pearls, where said pearls are dispersed in said matrix so as to generate intercommunicating cells,&#x2014;causing the solidification of the matrix of polymer or prepolymer to obtain said polymer foam including said hydrogel pearls, characterised in that it comprises the operation of subjecting the thus obtained foam to conditions which cause the dehydration of said hydrogel pearls so as to obtain a reduction of volume of said pearls and&#x2014;removing the dehydrated pearls by immersion in water of the polymer foam or by exposure of the foam to a flow of pressurized gas or water.
