  • New Saccharide Derived Monomers and Their Use in Water Treatment Polymers
    Carbohydrates ranging from monosaccharides to large oligosaccharides were functionalized with a single polymerizable a-methyl styryl group using reductive amination as the key synthetic step. These new monomers were then copolymerized with acrylic acid to give water treatment polymers with pendent
  • BSA Monomer-Dimer Elucidation with the BI-MwA (.pdf)
    Aggregation kills. Aggregated therapeutic proteins can provoke immune response and have reduced therapeutic effect. This has led to regulatory and industrial interest in identifying aggregates for elimination. Size-exclusion chromatography (SEC/GPC) has been a useful technique for the determination
  • Plastics that perform
    are the basic building blocks of plastics. Through the process of polymerization, monomers combine to create chemical chains called polymers. Polymerization usually takes place under heat and/or pressure. The term homopolymer refers to a polymer made from a single monomer. Copolymers come from two
  • PEVA Film and EVA Film
    EVA is a copolymer which is comprised of the monomers Ethylene C2H4 and Vinyl Acetate Monomer CH2=CHOOCCH3 conjoined to make the copolymer Ethylene Vinyl Acetate, or EVA for short. EVA lowers the seal initiation temperature and melting point of PE film. In low percentages, it has been used
  • No stress nylon
    .-diameter cavity in the steel casting that is part of every freight car bogey. Reaction-injection molding (RIM) combines two lowviscosity liquid streams consisting of a reaction catalyst and initiators (containing mostly monomer) inside the mold. The resultant polymer grows in molecular weight
  • Thermoplastic Elastomers
    between polymeric chains in a conventional, thermosetting rubber); the other monomer develops the soft, or amorphous segment, which contributes the rubbery characteristic. Properties can be controlled by varying the ratio of the monomers and the lengths of the hard and soft segments. Block techniques
  • Care and feeding of living hinges
    homopolymers ( single monomer), copolymers (mixed monomer), impact copolymers ( toughness enhanced), and random (nonordered monomers). And while injection molding is the manufacturing option of choice, other processes, such as extrusion, blow molding, and stamping, can also form hinges that flex more than
  • Characterisation of Polymers, Volume 1
    Characterisation of Polymers, Volume 1. Supported by more than 1200 references, this book covers the methodology used for the determination of metals, non-metals and organic functional groups in polymers, and the determination of the ratio in which different monomer units occur in copolymers.
