The synthesis of novel aliphatic bis(acenaphthelene) reactive monomers

Abstract

Novel aliphatic-bridged bis(acenaphthalene)s are synthesized and evaluated as potential precursors to high-temperature reactive monomers. It was found that as the length of the aliphatic bridging unit increased, the thermal stability of bis(acenaphthalene) increased and melting point decreased. The use of an alternative route for the introduction of the reactive vinyl group resulted in a dramatic increase in monomer purity. The increase in monomer purity resulted in the creation of a processing window that enabled samples to be melt cast prior to polymerization, greatly improving their suitability as high-temperature polymers. Polymerized samples were found to have high thermal stability, indicating they have potential as high temperature materials. V V C 2005 Wiley Periodicals, Inc.

Synthesis and characterization of a novel siloxane‐imide‐containing polybenzoxazine

“…The diverse applications of thermosetting polymers have attracted much interest 1–4. Polybenzoxazines (PBZs) are some of these materials that have attracted great interest from both academia and industry because of their superior properties 5–8.…”

The Effect of Particle Matrix Adhesion on the Mechanical Properties of Silica Filled Cyanate Ester Composites

“…This requires the use of additives such as inorganic fillers 2–5. Whilst there has been considerable interest in the toughening of cyanate esters,6–13 little has been done to evaluate the properties of moderately/highly filled cyanate ester composites 14…”
