    摘要： A biodegradable polymer includes a) 20 to 60% of a mixture of starch and/or a modified starch, b) 8 to 22% of starch plasticisers and processing agents c) 30 to 70% of one or more biodegradable aliphatic polyesters d) 1 to 10% of a layered silicate clay mineral. The silicate mineral is an organoclay which has been formed by reacting clay with an intercalating chemical to compatibilise it with the polymers so that the clay is exfoliated and makes the blend amorphous. The polymers may also include the usual additives including e) from 0 to 20% by weight of a polyol plasticiser f) from 0.1 to 1.5% by weight of a C12-22 fatty acid or salt or a destructing agent preferably urea and/or urea derivatives, and g) from 0 to 12% by weight of added water. The polyester may be modified by reaction with maleic anhydride.

    摘要： A roofing membrane which exhibits improved properties, particularly reduced propensity to blister, is produced by selecting a the group consisting of straight run asphalts with a rod & ball softening point in the range of from 80 to 130 degrees F.; oxidized asphalts, solvent washed asphalts, road tars, refined tars, and blends thereof; selecting a modifying polymer from a group consisting of: styrene-butadiene-styrene (nullSBSnull) block co-polymer, atactic polypropylene (nullAPPnull), and a combination of SBS and APP; modifying the bitumen by adding the polymer while the bitumen is in a molten state in a sealed mixing vessel; exposing the modified bitumen to a pressure less than ambient during or after modification while still in a molten state to allow release of entrained gases; and forming the roofing membrane from the molten modified bitumen.

    摘要： A halogenated polysaccharide is provided having a halogen content of from about 1.0 wt. % to about 85 wt. % based on the total weight of the halogenated polysaccharide and having an average chain length of at least 6 monosaccharides. Methods of halogenating a polysaccharide to form a halogenated polysaccharide are provided that can be performed in the presence or absence of a proton solvent. Compositions such as articles of manufacture containing a halogenated polysaccharide and methods of producing such articles are also provided. The article of manufacture can also include one or more additional polymers, for example, polyvinylchloride (PVC). The article of manufacture can be, for example, a flooring tile, flooring plank, or carpet. Halogenated polysaccharides and products containing the same are bio-based, environmentally sustainable replacements or complements to existing polymers and polymer products.
