Synthesis and Characterization of a Fluorinated Phenolic Resin/phenolic Resin Blend
Journal of Macromolecular Science, Part B, 2015ABSTRACTFluorine atoms were introduced into the molecular chain of a phenolic resin (PR) by a two-step acid synthesis process to improve its thermal and hydrophobic properties. The successful synthesis of a fluorinated phenolic resin/phenolic resin blend (F-PR/PR) was proven by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic ...

AbstractA new method of curing phenolic novolac resins by means of cyclic formals under the catalytic influence of strong acids is given. It was proved that the formals react with the novolac molecules to form a highly crosslinked resite structure. As a practical consequence of this novel curing process it is possible to use the new resins at low or ...

Phenol-formaldehyde resin was developed as the first wholly synthetic polymer at the beginning of the 20th century and was called Bakelite. From the first resins others varieties have been developed and phenol-formaldehyde resins now designates a group of resins with varying properties made from different phenols and aldehydes.
