| 20110071238 | ALIPHATIC-AROMATIC BIODEGRADABLE POLYESTER - The invention refers to aliphatic-aromatic biodegradable polyesters obtained from aliphatic dicarboxylic acids, aromatic acids of renewable origin and diols, and also to blends of said polyesters with other biodegradable polymers of either natural or synthetic origin. | 03-24-2011 |
| 20110020660 | BIODEGRADABLE POLYESTER, PREPARATION PROCESS THEREOF AND PRODUCTS COMPRISING SAID POLYESTER - The invention relates to a biodegradable polyester, particularly suitable for extrusion coating, comprising units deriving from at least a diacid and at least a diol, with long chain branches (isometric with respect to the main chains of the polyester) and essentially gel-free, characterized by optimum adhesion to paper, excellent sealability and processability in extrusion coating systems. Said biodegradable polyester is obtainable through a reactive extrusion process starting from a substantially linear polyester precursor with defined viscosity and concentration of reactive sites which allow transformation of a few chains of the polyester precursor into isometric branches of this polyester. A further object of the present invention is a laminate product composed of at least a backing, preferably paper, and of at least a first layer composed of polyester according to the invention. | 01-27-2011 |
