Method for stabilizing halogen-free thermoplastic recyclates, stabilized plastic compositions, and molding compounds and molded parts produced therefrom
The invention relates to a method for stabilizing halogen-free thermoplastic recyclates or pre-damaged plastics against oxidative, thermal, and/or actinic degradation. In the method according to the invention, at least one alditol or cyclitol is introduced into a halogen-free thermoplastic recyclate as a component, and optionally in addition thereto, at least one primary antioxidant and/or at least one secondary antioxidant is introduced into a halogen-free thermoplastic recyclate. By virtue of the method according to the invention, plastic recyclates can be stabilized against oxidative, thermal, and/or actinic degradation with a high degree of effectiveness and in a very environmentally friendly and inexpensive manner. The invention additionally relates to corresponding recyclate-based plastic compositions, to molding compound and molded parts produced therefrom, to stabilizer compositions, and to the use thereof for stabilizing halogen-free thermoplastic recyclates against oxidative, thermal, and/or actinic degradation.

METHOD OF MAKING CELLULOSE BIOPLASTICS
The present invention includes a bioplastic and a method of making a bioplastic comprising the steps of: dissolving a low quality cellulose biomass in a solvent, wherein low quality is defined as having little to no textile value; regenerating cellulose fibers by removing the solvent; plasticizing the cellulose fibers in the presence of a polyol into a plasticized film; and hot pressing the plasticized film into the bioplastic.
