An adhesive blend is described that can include a semi-crystalline copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and at least one C 4 to C 20 ±-olefin, the copolymer having a weight average molecular weight (Mw) from about 15,000 to about 200,000; an melt index (MI) from about 7 dg/min to about 3000 dg/min as measured by ASTM D 1238(B), and a (Mw/Mn) of approximately 2. Various production processes are also described. Also described are adhesive compositions and methods for making adhesive compositions having polymers or polymer blends with melt flow rates (MFRs) equal to and above 250 dg/min. at 230NC. Certain specific embodiments of the invention involve the use of a free radical initiator, e.g., a peroxide.
摘要:
The present invention relates to ligands and the synthesis of those ligands for use in metallocene complexes. More particularly, the present invention relates to the synthesis of diarylsilyl bridged biscyclopentadienes using diarylsilyldisulfonates. Even more particularly, the present invention describes Group IV metallocenes containing diarylsilyl bridged bis-cyclopentadienyl ligands prepared from contacting a diarylsilyldisulfonate with an organometallic indenyl reagent.
摘要:
The present invention relates to novel retinol derivatives, the methods of preparation and the uses thereof. According to the present invention, retinol derivatives comprise carboester linkage between di-, tri-, polypeptide having functional group of COOH and retinol. Retinol derivatives in the present invention comprise carboester linkage between amino acid having functional group of di-COOH and retinol. Retinol derivatives comprise carboester linkage between retinol and the compounds having the function group of COOH and multiple double bonds on carbon chain. Retinol derivatives in the present invention comprise carboester linkage between retinol and the compounds having the functional group of di-COOH and one double bond. Retinol derivatives in the present invention comprise ether linkage between the compounds with OH functional group and retinol.

This invention is also directed to pharmaceutical compositions containing the compounds of the invention, and methods of using the compounds to treat disease-states characterized by thrombotic activity.
摘要:
Pharmaceutical compositions are disclosed suitable for parenteral administration having anti-inflammatory, analgesic, and anti-pyretic properties, which consist of a therapeutically effective amount of d,l or l-lysine salt of R,S or S-ibuprofen as active ingredient dissolved in sterile water to form a solution in the absence of an inert atmosphere and either substantially free or absolutely free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere. Also disclosed are methods employing the new compositions in the treatment of pain and inflammation, in reducing fever and in treating patent ductus arterious or intraventricular hemorrhage in prematurely born neonates.
摘要:
There are provided pharmaceutical formulations with improved oral absorptivity and injections that contain, as active ingredients, high concentrations of benzamide derivatives and their pharmaceutically acceptable salts, which are useful as histone deacetylase inhibitors. A pharmaceutical solution is prepared by dissolving a benzamide derivative or a pharmaceutically acceptable salt thereof in an organic solvent and/or acidic liquid, and a pharmaceutical formulation is prepared by adding a surfactant, an acidic substance and/or a polyethylene glycol. The present invention has enabled dissolution of benzamide derivatives or their pharmaceutically acceptable salts at high concentrations, to prepare practical injections and oral liquid formulations and improve absorptivity with oral administration.
