Investigation of the polymerization process and property modification of metallocene-based cycloolefin (COC) shows that this monomer-catalyst combination enables synthesis of a new class of transparent thermoplastic polymers. Metallocene catalysis of

Starting with the theoretical considerations of our previous papers [1,3], some practical aspects concerning the shift procedures of rheological data are analysed. The latter can be used for the construction of both isotherm and isochrone master curv

In a previous publication a new concept has been presented for the composition dependence of the glass transition in compatible polymer blends. The concept starts with the idea that besides conformational energy barriers, contacts due to interaction

Starting with the idea that, besides conformational energy barriers, surface contacts are responsible for both conformation and ‘free’ volume distribution, a new concept is developed to describe the glass transition in compatible polymer blends.

It is shown that composition dependence of glass-transition in the compatible poly(styrene)-poly(vinylmethylether) blend exhibits deviations from additivity rules derived in the supposition of continuity of the thermodynamic excess functions of mixin

Starting from EYRING's transition state theory it is demonstrated for systems obeying the superposition principle that the frequency shift factors of isotherm mastercurves of the viscoelastic functions as well as the temperature shift factors of the

Complexes between diphenylcarbamido-dicarboxybenzene and 1-methyl-2-pyrrolidinone, 1/4 and 1/2 M, are obtained by reacting pyromellitic dianhydride with aniline in the solvent 1-methyl-2-pyrrolidinone. Decomplexation and imidization of this diamic ac

The limitations of the WLF-relation are discussed with respect to their inherent demands concerning universality. The problem of the reference temperature is discussed in some detail, and their constants are related to the temperature T∞ where the

The applicability of an approach is tested experimentally, which interrelates the frequency as well as the temperature shift of isotherm and isochrone viscoelastic data with the apparent activation energy of the viscous flow. The procedure is based o
