  • copolymers
  • en] We investigate the microscopic morphology of thin films of symmetric triblock copolymers synthesized via a two-step "living" radical polymerization of n-butylacrylate and methyl methacrylate. (ac.be)
  • These copolymers with low poly(methyl methacrylate) contents constitute a new class of potential thermoplastic elastomers with higher service temperature and oxidation resistance compared to conventional polydiene−polystyrene-based thermoplastic elastomers. (ac.be)
  • Morphological characterizations revealed a well-ordered lamellar microstructure and a unique three-phase morphology of the DABCO block copolymers, which involve a soft phase, a hard phase, and an ionic aggregates domain dispersed within the hard domain. (vt.edu)
  • An improved process for the preparation of thermoplastic vulcanizates from butyl rubbers by hydrosilylation crosslinking of acrylic or alkacrylic functionalized copolymers of isobutylene and paramethylstyrene is disclosed. (google.es)
  • Polyamide
  • Reporting on the work of an international team of scientists actively involved in the study of thermoplastic elastomers (TPE) based on polyesters, polyamides, and polyurethanes, this book is the first to provide a detailed description of condensation TPE with close attention paid to polyamide-based systems.

  • Solvent
  • Polymer morphology may also be important in single-component or homogeneous multi-component systems when the molecular-level orientation of polymer chains produces either a desired, or unwanted, effect One such case is seen in polycarbonate systems that undergo "solvent induced" crazing when exposed to various solvents.

  • rubber
  • Synergistic effects of two kinds of rare earth oxides (REOs), samarium oxide (Sm 2 O 3 ) or lanthanum oxide (La 2 O 3 ) on the intumescent flame retardancy of Nylon 1010/ethylene-vinyl-acetate rubber (EVM) thermoplastic elastomers (TPE) were studied systemically. (springer.com)
  • Lu X, Zhang H, Zhang Y (2014) Structure and properties of nylon 1010/ethylene-vinyl acetate rubber-based dynamically vulcanized thermoplastic elastomers filled with SiO2. (springer.com)
  • As a result, BIIR and CIIR can be cocured more readily in contact with other elastomers making up a rubber product. (britannica.com)
  • vulcanizate
  • 3. A thermoplastic vulcanizate according to claim 2, wherein said alkacrylic group is derived from metal salt of acrylic or methacrylic acid. (google.es)
  • 9. A thermoplastic vulcanizate according to claim 8 further including residual platinum from a platinum containing hydrosilylation catalyst. (google.es)
  • phase
  • For instance, some desirable phase morphologies may be difficult to achieve, requiring high processing temperatures or intensive mixing. (allindianpatents.com)
  • The toughening was achieved with a finely dispersed P(LA/CL)U or copoly(L-lactide/ε-caprolactone) elastomer phase in the matrix PEU. (aalto.fi)
  • LDPE
  • Morphology of fractured surface of LDPE/EPDM shows that with increase in EPDM content, the size and depth of the cavity becomes larger and deeper indicating higher ductility. (scirp.org)
  • applications
  • The strong hydrogen bonding or ionic interaction also directs self-assembly to hierarchical microstructures, which enables many applications including thermoplastic elastomers and energy storage devices. (vt.edu)
  • structure
  • In addition to these considerations, the structure and morphology of polymeric materials make selection and specification of seal materials much more complicated than the standard materials used in mechanical engineering (e.g. aluminium or steel). (skf.com)
