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:
The present invention relates to a rubber composition containing at least one diene-based elastomer, a starch/plasticizer composite and an adduct of maleic anhydride and polybutadiene, and to pneumatic tires having at least one component comprised of such rubber composition. Such tire component can be, for example, its circumferential tread or other component of the tire.

摘要:
Used and manufacturing scrap asphalt shingle material is processed into a relatively course material comprising pieces or flakes of a maximum predetermined size, preferably with a relatively low aggregate content. The flakes are finish processed into ground cover and/or erosion control products, with advantage taken of the larger size and low aggregate content. Processing of the flakes include (i) tumbling and simultaneously heating the flakes and a dry powder, (ii) embedding a surface treatment material into the heated flakes, and either (iii) drying the flakes for use as loose ground cover, or (iv) compressing the flakes into a mat product. The flakes may be produced by an initial process that includes (i) shredding the used and scrap shingle material into pieces of a predetermined maximum size, and (ii) separating the shredded material into (a) fine material and (b) course material. In this instance, the course material comprises the larger flakes that are subsequently processed into the ground cover and erosion control products; and the fine material comprising the smaller sized pieces of shredded shingle material and loose aggregate dislodged from the larger sized pieces during the shredding process may be forwarded for finish processing into shaped products adapted to take advantage of the high aggregate content therein.
摘要:
The present invention encompasses cellulose ether blends comprising a) cellulose ether, b) from 0.1 to 10% by weight of an additive selected from starch, starch ether, guar, guar ether and xanthan, based on the dry cellulose ether, c) optionally from 0.05 to 1% by weight of polyacrylamide, based on the dry cellulose ether, and d) optionally further additives, characterized in that additive b) has been metered in as an aqueous solution or as a powder and polyacrylamide c) has been metered in as an aqueous solution to a water-moist cellulose ether having a moisture content in the range from 25% to 75% by weight, based on the weight of the moist cellulose ether, with mixing and optionally further addition of water, and processes for making and using the blends.
摘要:
The present invention provides a variety of extended polyacrylic acid based binder compositions comprising a low molecular weight polyacrylic acid (typically hypophosphite or sulfite terminated), a crosslinking agent (such as triethanolamine or glycerol) and one or more water soluble materials, such as lignin, low molecular weight starch and soybean protein. The extended binder composition of the present invention provides a lower cost binder composition without degrading the performance and may be selected to alter one or more characteristics of the basic binder composition such binder wetting, emulsion compatibility, dust suppression and wash water flow properties.
摘要:
Compositions for securing pre-pasted and non-pre-pasted wall coverings to a surface that is to be decorated are provided. The present compositions are aqueous colloidal dispersions or polymeric solutions comprising from about 3% to about 30% solids. The present compositions comprise water, an alkali, from about 2.5% to about 25% by weight of an alkali-soluble, polyvinyl acetate-crotonic acid copolymer, a thickener, and a glycol.
摘要:
An environmentally friendly stable aqueous optionally structured water-resistant architectural coating composition (especially a paint) containing a film-forming binder polymer composed of a starch modified by the presence of carboxylic acid or inorganic carboxylate groups and bonded (probably grafted) to chains of copolymerized mono-ethylenically unsaturated monomers (e.g. nullacrylicnull, nullvinylnull or nullstyrenicnull copolymers) permitting a stable aqueous dispersion of the binder polymer to be made which retains good water-resistance in the dried paint. The modified starch allows paints to be made with less dependence on materials obtained from non-renewable resources whilst retaining a low water-sensitivity.
摘要:
The present invention relates to the use of a pigment form or pigment concentrate comprising of an organic pigment, and optionally an inorganic filler and/or an organic additive for coloring of seeds. Seeds colored by the dry pigment forms or pigment concentrates show an homogeneous color and in some cases growth promotion effects.
