  • thermoplastic
  • 1) Recognize the main differences, characteristics and features of the three classes of polymers, i.e. thermosetting, thermoplastic and elastomers. (unisalento.it)
  • hydrophobic
  • Therefore, most of recent formulation strategies attempting practical dosage forms have involved efforts to avoid exposing proteins to water-oil interfaces, water-air interfaces, cross-linking reagents, and hydrophobic environment of the polymer matrix of sustained-release systems ( 3 , 4 ). (pubmedcentralcanada.ca)
  • As the temperature of the elution increased, when the chains behave in a more hydrophobic manner, the elution times increased for each of the analytes for the given range. (wikipedia.org)
  • Side-Chains
  • Iodoacetyl functional groups can be added to selectively bind cysteine side chains and this method is often used to immobilize peptides. (wikipedia.org)
  • The first and third scales are derived from the physiochemical properties of the amino acid side chains. (wikipedia.org)
  • They all react with amine groups and will therefore also bind to amine groups in the side chains of amino acids such as lysine - for this reason it is necessary to be careful in interpreting chromatograms to ensure that the right spot is chosen. (wikipedia.org)
  • polymeric
  • 4) Select a proper polymeric material, or a blend of polymers, for a specific application. (unisalento.it)
  • Moreover, high electro- optical activity of the corona poled polymeric film is determined, and the phase separation which usually occur in the side-chain system is effectively minimized. (spie.org)
  • Chain topology controls many critical properties (e.g., crystallization, solubility, and rheological behavior) of polymeric systems. (nap.edu)
  • Polymeric rotaxanes, in which the chain backbone is threaded through a series of macrocycles, have also been reported recently. (nap.edu)
  • organic-inorganic
  • The unique self-assembly properties of star shaped polymers make them a promising field of research for use in applications such as drug delivery and multiphase processes such as separation of organic/inorganic materials. (wikipedia.org)
  • hydrogels
  • Disposable diapers where they absorb urine, or in sanitary napkins Contact lenses (silicone hydrogels, polyacrylamides, polymacon) EEG and ECG medical electrodes using hydrogels composed of cross-linked polymers (polyethylene oxide, polyAMPS and polyvinylpyrrolidone) Water gel explosives Rectal drug delivery and diagnosis Encapsulation of quantum dots Breast implants Glue Granules for holding soil moisture in arid areas Dressings for healing of burn or other hard-to-heal wounds. (wikipedia.org)
  • composition
  • In the gradient copolymer, there is a continuous change in monomer composition along the polymer chain (see Figure 2). (wikipedia.org)
  • The wide range of composition possible in a gradient polymer due to the variety of monomers incorporated and the change of the composition results in a large variety of properties. (wikipedia.org)
  • Generally the composition has a narrow polydispersity index (PDI) and the molecular weight increases with time as the polymer forms. (wikipedia.org)
  • Some of the most interesting characteristics exhibited by star-shaped polymers are their unique rheological and dynamic properties compared to linear analogues of identical molecular weight and monomer composition. (wikipedia.org)
  • Both by weight and volume, gels are mostly fluid in composition and thus exhibit densities similar to those of their constituent liquids. (wikipedia.org)
  • chemically
  • The proanthocyanidin polymers can be chemically synthesized or can be isolated from a Croton or a Calophyllum plant species. (google.com)
  • wherein
  • The invention particularly pertains to a multilayer structure containing an improved sealant layer and a polypropylene layer, wherein the sealant layer is made from a homogeneously branched ethylene polymer having particular molecular weight characteristics and a second ethylene polymer. (google.ca)
