Polymer Characterization: Polymer Molecular Weight Determination
Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...
متن کاملPreparation and molecular weight determination of soya-beans and benniseed oil-modified alkyd resins
Alkyd resins were prepared into four different sets by varying the percentage concentrationof the glycerol content. Various properties such as the viscosity, Surface drying time, solubilityand color of the alkyd resins were evaluated for the various sets. The alkyd resin with the highestglycerol content was the most viscous, brownish in color and having the highest molecularweight this is due t...
متن کاملDetermination of low molecular weight heparin in clinical laboratory.
The applicability was investigated of automated spectrophotometric heparin assays and three clotting assays for determination of two low molecular weight (LMW) heparin fractions: Org 10172 and DxN10 and two infractionated commercially available heparins. The relative activity of the two commercially available heparins was similar in the anti-Xa assay, in the anti-IIa assay and in 3 clotting ass...
متن کاملModernization of Enoxaparin Molecular Weight Determination Using Homogeneous Standards
Enoxaparin is a low-molecular weight heparin used to treat thrombotic disorders. Following the fatal contamination of the heparin supply chain in 2007-2008, the U.S. Pharmacopeia (USP) and U.S. Food and Drug Administration (FDA) have worked extensively to modernize the unfractionated heparin and enoxaparin monographs. As a result, the determination of molecular weight (MW) has been added to the...
متن کاملDetermination of Soluble CD14 Molecular Weight Variants in Human Plasma
Inflammation is an important underlying biochemical process of many fatal diseases and infections. Inflammation can be an acute response to trauma or infection, or chronic in cardiovascular diseases like atherosclerosis. In the United States, in 2011 atherosclerosis was responsible for 16% of all deaths, and in 2015 an estimated 200,000 people will die from sepsis [1, 2]. The Cardiovascular Hea...
