摘要:
A polymer coating for medical devices based on a polyolefin derivative. A variety of polymers are described to make coatings for medical devices, particularly, for drug delivery stents. The polymers include homo-, co-, and terpolymers having at least one olefin-derived unit and at least one unit derived from vinyl alcohol, allyl alcohol and derivatives thereof.
摘要:
A mixture of a polyester or a polyamide, such as poly(ethylene terephthalate) PET, and a suitable stabilizer selected from the group consisting of certain Mannich base compounds, when extrusion compounded exhibits a lower residual acetaldehyde content than does PET or polyamide alone when similarly treated. The invention pertains to any polyester or polyamide used in the manufacture of molded articles, fibers or films, for instance bottles or containers which are used to store consumer materials, for example food, beverages and water.
摘要:
There is provided a biodegradable composition as obtained from a melt comprising starch, a plasticizer and at least one member selected from alkenol homopolymers and/or alkenol copolymers which are combined under conditions sufficient to ensure uniform melt formation, characterized in that the at least one member is present in the composition at a concentration of from 10 to 120 parts per 100 parts of dry starch. The invention further relates to methods of making the composition, and to articles made from said composition.
摘要:
The present invention relates to a method for isolating proteins from a solution containing the proteins. The invention also relates to a method for the chromatographic separation of proteins. The present invention also relates to crosslinked hydroxylic polymer particles functionalized with temperature-responsive copolymer, and to methods of preparing such particles.
摘要:
The invention relates to a dispersion containing (i) at least one liquid polymer and (ii) at least one polymer particle mixture comprising at least one meltable solid substance and at least one copolymer (C). Said at least one copolymer (C) is a copolymer consisting of at least one a,ß-ethylenically unsaturated monomer and at least one polymerisable polymer from the class of liquid polymers in (i). The invention also relates to a method for the production of said dispersion, to the use of said dispersion for producing polyurethanes, and to a method for producing polyurethanes, according to which at least one dispersion of said type is reacted with at least one polyisocyanate.
摘要:
An article having barrier properties is provided. The article includes a nanocomposite having barrier properties dispersed in a polyolefin resin to have superior mechanical strength and form a strong barrier to oxygen, organic solvent, and moisture.
