This study was aimed at using micro-Raman spectroscopy for the local characterisation of phase separated blends based on epoxy polymer and copolyethersulphone thermoplastic. The morphologies developed in the blends containing 25% by weight of thermop

The possibility of using Raman spectroscopy to determine the local thermoplastic content within blends of epoxy resins and copolyethersulfone was studied. The required calibration of the Raman data is presented here. It was obtained by multivariate m

Methods have been developed to determine by Raman spectroscopy the epoxide conversion in a 4,4'-diaminodiphenylsulfone (DDS)-cured epoxy resin as well as in blends of this resin with copolyethersulfone thermoplastic. The proposed spectral treatments

Reactive thermoplastics are increasingly used as toughening modifiers for epoxy resins. A way to understand the influence of the reactive end-groups on the toughening and curing mechanisms is to observe in situ the reaction between the thermoplastic

A series of crosslinkable maleimide-ended poly(ether sulfone)s has been prepared using a range of molecular masses. The effect of the crosslinking reaction on the glass transition temperatures (T(g)s) is observed. In the range of molecular masses stu

New high-temperature amorphous polymers with chlorine, amine, and maleimide chain-ends have been synthesized by nucleophilic polycondensation and fully characterized by C-13-NMR,H-1-NMR, and potentiometric titration. From chain-end determination, num

The synthesis of a new poly[aryl ether(ketone-co-sulfone)] proceeds through a chemical mechanism similar to that in the poly(ether ether ketone) and poly(ether sulfone) polymerizations. It is basically a nucleophilic substitution of a dihalogenated s

From a detailed study of the syntheses and physical properties of semicrystalline poly[aryl ether(ketone-co-sulfone)] model compounds, this paper leads to a better understanding of the chemistry of the polymer synthesis and of its thermal behaviour.

The nucleophilic cleavage of differently activated aryl ethers by a fluoride anion is studied. Two sulphone groups in para positions to the ether link appear to activate this sufficiently to allow its nucleophilic substitution by F- to occur from 280

Molecular design, microstructure, and physical properties of polymers are strongly related to each other. A better understanding of their interdependence will give the polymer chemist useful ideas for the synthesis of new macromolecules. The present
