Abstract: The invention relates to filter material for inclusion in the filter or filter element of a 5 smoking article, said filter material comprising polylactide fibers and a plasticizer. The invention also relates to filters or filter elements comprising the filter material, and smoking articles comprising the same.

Abstract: The present invention relates to water-dispersive biodegradable compositions which may be formed into films and fibers. The present invention also relates to polymer blends comprising polylactide and water-soluble polymers. More particularly, the present invention relates to the use of grafted copolymers (PLA-grafted water-soluble polymers) for the compatibilization of PLA and water-soluble polymers. Such reactive compatibilization of immiscible polymer blends is achieved in such a way that main blend components are covalently bonded. In addition, such reactive compatibilization can be carried out by reactive extrusion.

Abstract: The present invention relates to filter materials comprising cellulose acetate and polylactide in a ratio of about 95:5 to about 75:25 by weight, and to filters (2) or filter elements comprising such filter materials. The invention also relates to smoking articles (1) comprising the filter materials, filters (2) or filter elements.

Abstract: The present invention relates to compositions comprising a blend of cellulose acetate and a water soluble polymer. In some embodiments, the composition is water dispersive and/or biodegradable. Embodiments of the invention also relate to processes for preparing such compositions, and to materials and products including such compositions.

Abstract: The invention relates to filter material for inclusion in the filter or filter element of a 5 smoking article, said filter material comprising polylactide fibres and a plasticizer. The invention also relates to filters or filter elements comprising the filter material, and smoking articles comprising the same.

Abstract: The present invention relates to compositions comprising a blend of cellulose acetate 5 and a water soluble polymer. In some embodiments, the composition is water dispersive and/or biodegradable. Embodiments of the invention also relate to processes for preparing such compositions, and to materials and products including such compositions.
