  • Synthesis and Characterization of Polyvinyl Alkyl Ester and Polyvinyl
           Alcohol Homopolymers and Blends of Polyvinyl Alkyl Esters

    • Authors: Ronald P. D’Amelia; Masashi W. Kimura, Joseph Mancuso
      Pages: 1 - 12
      Abstract: Polyvinyl alkyl esters (PVAe) are a family of macromolecules in which the ester side chains (pendant groups) increase in molar mass and hydrophobicity and decrease in structural polarity as the number of carbons in the pendant group increases. These PVAe are commonly used in adhesives, industrial coatings, plasticizers, textile finishes, chewing gum bases, and paint thickeners. The most significant polymer in the family of PVAe is polyvinyl acetate (PVAc), which is the precursor for making polyvinyl alcohol (PVOH), the largest volume water-soluble, non-toxic, biodegradable, and biocompatible polymer in the world used in the manufacture of pharmaceuticals, cosmetics, food industries, laundry detergents, and freshwater sports fishing. In this study, the goal is to synthesize polyvinyl alkyl ester homopolymers of various molecular weights by esterifying polyvinyl alcohol with alkyl anhydrides. The study also includes the synthesis of various polyvinyl alcohol homopolymers from different polyvinyl acetates via hydrolysis. These polymers were studied via gel permeation chromatography (GPC), multi-angle laser light scattering (MALLS), intrinsic viscosity, elemental analysis, Fourier-transform infrared spectroscopy (FT-IR), and nuclear magnetic resonance spectroscopy (NMR). Blends of polyvinyl alkyl ester homopolymers with defined compositions were also studied using quantitative FT-IR.

  • Molecular Origin for Strong Agarose Gels: Multi-Stranded Hydrogen Bonding

    • Authors: Masakuni Tako; Takeshi Teruya, Yukihioro Tamaki, Keiko Uechi, Teruko Konishi
      Pages: 13 - 19
      Abstract: Agarose gels are currently used in separation, purification, and characterization of DNA, RNA, proteins, and polysaccharides in gel electrophoresis, gel filtration, affinity chromatography, and ion chromatography techniques. Specifically, it is used in PCR (Polymerase Chain Reaction) test. Although, double stranded intermolecular hydrogen bonding between OH-2 and 3,6-ring oxygen atoms of 1,4-linked anhydro-α-L-galactopyranose residues on different molecules take place, triple- or multi-stranded secondary association occur with increasing concentration. The multi-stranded gelation mechanism of agarose molecules is the first to report. The associated agarose molecules play a dominant role in the centre of tetrahedral cavities that are occupied by ice-like hydrogen bonded water molecules which are caused thermodynamically by cage and hydrophobic effects. Many investigations the gelling properties of the polysaccharides have been undertaken to elucidate the structure-function relationship, but no other researchers have established the mechanisms at the molecular level including water molecules. There are structural and theoretical consistencies in our investigation. This paper provides important information not only academia, but also to industrial fields, such as bio-physicochemical analysis, food, cosmetics, agriculture, pharmaceuticals, drug delivery, drug storage, tissue engineering, and biotechnology.
