20110086950 | MASTERBATCH AND POLYMER COMPOSITION - The present invention relates to a method of preparing a biodegradable polymer composition, said method comprising melt mixing a first biodegradable polyester and a masterbatch, wherein said masterbatch has been formed separately by melt mixing in the presence of a transesterification catalyst a polysaccharide, a second biodegradable polyester and a biodegradable polymer having pendant carboxylic acid groups. | 04-14-2011 |
20110196071 | ELASTOMERIC COMPOSITIONS BASED ON ESTERS OF A STARCHY MATERIAL AND METHOD FOR PREPARING SUCH COMPOSITIONS - An elastomeric composition, contains:—at least 5% and at most 70% by weight of an ester of a starchy material, which has a degree of ester substitution (DS) of between 1.0 and 3.0, preferably between 1.2 and 3.0,—at least 5% and at most 40% by weight of a plasticizer of this ester of starchy material, the plasticizer preferably being other than water, and—at least 25% by weight and at most 90% by weight of an elastomeric non-starch polymer. | 08-11-2011 |
20130158169 | MOLDED ARTICLES OF STARCH-POLYMER-WAX-OIL COMPOSITIONS - Molded articles formed from compositions comprising thermoplastic starch, thermoplastic polymers, and oils, waxes, or combinations thereof are disclosed, where the oil, wax, or combination is dispersed throughout the thermoplastic polymer. | 06-20-2013 |
20130338271 | DEGRADABLE MATERIALS - The present disclosure relates to a degradable material comprising (a) from about 60 weight percent to about 97 weight percent of a first material based on the total weight of the degradable material, and (b) from about 3 weight percent to about 40 weight percent of a second material based on the total weight of the degradable material, where the second material is an oligomer comprising lactate and giycolate. In another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a Tg less than 56° C. In still another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a tan delta peak of less than 65° C. It has been surprisingly found that the degradable materials according to the present disclosure provide physical properties that are not inherent to poly lactic acid alone. It has also been surprisingly found that the degradable materials disclosed herein provide improvements with respect to the processability, production costs, flexibility and ductility without decreasing their degradability. | 12-19-2013 |
20150045480 | Starch-Based Hot Melt Adhesive - An exemplary embodiment of the present invention provides starch-based hot melt adhesive comprised of a composition including starch, a thermoplastic polymer, a tackifier, a plasticizer, and an adhesion promoter. The hot melt adhesive according to the exemplary embodiment of the present invention contains about 25 to 55 weight % of the starch which is infinitely renewable biomass, and, thus, it is less harmful and more eco-friendly and has a reduced manufacturing costs and is less sensitive to exhaustion of petroleum-based resources, as compared with the conventional hot melt adhesive mainly containing a petroleum-based material. Further, the hot melt adhesive according to the exemplary embodiment of the present invention imparts excellent adhesion strength and workability at the time of adhesion between different kinds of adherends such as a hydrophobic adherend and a hydrophilic adherend and can be applied to various fields such as packaging, bookbinding, construction, woodworking, and textile fields. | 02-12-2015 |
20160160011 | PROCESS FOR PRODUCING A HYDROPHOBIC COMPOSITE BIOELASTOMER COMPRISING STARCH - 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. | 06-09-2016 |
