In one embodiment, a process of manufacturing paper or other products is provided using a composition comprising a mixture of 25% to 80% calcium carbonate along with a biodegradable biopolymer matrix made from renewable resources including polylactic acid (“PLA”), soy proteins, polyhydroxyalkanoate (“PHA”), polyhydroxybutyrate (“PHB”), and/or starch from corn, wheat, tapioca, potatoes, or similar renewable resource products. | 07-14-2011 |
| 20130046044 | Biodegradable Polymers and Methods for the Preparation Thereof - The present invention relates to biodegradable polymers, and especially polyacrylic and/or polyaspartic acid based biodegradable polymers. Further, the present invention relates to methods for the preparation of the present biodegradable polymers and the use thereof as, for example, protective layer or packaging material. Specifically, the present invention relates to methods for preparing a biodegradable polymer comprising: a) preparing an acidic mixture of polyacrylic and/or polyaspartic acid, sodium ions, one or more oligosaccharides, or derivatives thereof, and water, wherein the resulting mixture has a pH equal to or lower than 5; b) maintaining the temperature of said acidic mixture in a range of from 80° C. to 130° C. until an homogeneous suspension is obtained; and c) adding polyvinyl alcohol (PVA) and one or more polycarboxylic acids, or derivatives thereof, to the mixture of step (b) while maintaining the temperature in a range of from 80° C. to 130° C. until the biodegradable polymer is formed. | 02-21-2013 |
