qenesoon heat transfer oil for polycondensation

  • Process for the thermal polymerization,

    Even here, however, problems have been discerned with selection of the heat-transfer agent. For example, oil (see French Patent FR-PS 694,690) has the disadvantage that it mixes with the low-viscosity monomeric materials at temperatures of 60° to 100° C. or solubilizes the monomers wherever they are accessible to the oil through the pores of ...

  • Polycondensation Reaction - an overview |

    On heat-treatment of aromatic hydrocarbons, polycondensation reactions occur resulting in formation of mesophase which is the precursor of graphitizable carbon fibers and carbons. Changes in the molecular structures and molecular arrangements during this process are monitored as electronic transitions in the Vis and near-IR region.

  • Preparation of Microcapsules Containing Phase Change ...

    The bulky PCM is given the extremely large heat transfer area by being microencapsulated . However, supercooling is easy to occur due to the limited smaller hollow. Furthermore, the microcapsules made of a p o-lymer shell and PCMs such as paraffin wax with low thermal conductivity have a less heat conductivity.

  • Polycondensation, Step-polymerization - LIST

    Polycondensation or step-growth polymerization is often used for the processing of adhesives, coatings, engineered plastics, fibers, films and many high-performance polymers. During the polycondensation reaction, the volatile monomers are evaporated from the lower molecular weight pre-polymers to form polymers with a higher molecular weight.
