✦ Synopsis

The temperature and frequency dependences of complex shear modulus and mechanical losses were studied for epoxide resin filled with the same epoxide resin, i.e. using filler of the same chemical nature. Samples with different amounts of the filler have different physical structures. Experimental results have been discussed on the basis of WLF-method and the free volume concept. It was shown that the viscoelastic properties of the epoxy binder hardened in the presence of the same resin hardened beforehand differ from the properties of the resin hardened without filler. The fractional free volume at the glass temperature was found not to be a universal constant but depends on the physical structure of the system.

To date, most interpenetrating polymer networks (IPNs) are developed for slow processes such as casting or coating. For industrial manufacturing, fast-reactive polymer processing is often required. Simply increasing the amount of catalyst and/or free-radical initiator shows some limitations. Also, i

The polymerization of a mixture of N-vinylcarbazole (NVC) and pyrrole (PY) by 0-chloranil in toluene yields an insoluble black polymer P(PY-NVC) which exhibits properties distinct from PPY or PNVC. The inclusion of either monomer moieties in P(PY-NVC) has been endorsed by IR spectroscopy. Kinetics o
