Based
on our professional expertise, we are pleased to offer our services
in the topics listed below. Our Department has a long history
of successful contracts and cooperations bridging the gap between
the academic and business sectors. Our former customers/partners
include Shell, General Electric, BASF, Clariant
and many other national and international firms, from small
enterprises to multinational corporations.

Polymer Synthesis
Synthesis
of polyisobutylenes with well-defined molecular weight,
exact chain-end functionality and low polydispersity (suitable
for use as standard) on the scale of up to 100 g/batch.
Gel Permeation Chromatography (GPC)
For polymers soluble in tetrahydrofuran:
1. Estimating average molecular weights (Mn, Mw, Mz) and average
intrinsic viscosities [h], and also
their distributions. Based on universal calibration
curves and using a double detector-system comprised of a Viscotek
differential refractometer (RI) and a differential viscometer
(DV) connected in parallel.
2. Estimating average molecular weights (Mn, Mw, Mz) based on
light scattering analysis. Registered by a miniDawn
detector supplied by Wyatt Technology.
3. Determining branching numbers in branched or hyperbranched polymers.
4. Determining refractive index increment (dn/dc) with an
interferometric detector (Optilab DSP supplied by Wyatt
Technology)
Amphiphilic Conetworks
These
promising novel materials
are synthesized only in a few specialized laboratories worldwide;
our Department is one of the pioneering research groups in this
field. On order or in R&D cooperation we are able to offer:
-
synthesis of various types of amphiphilic conetworks - their extensive characterisation involving physical, chemical
(and certain types of biological) assaying. |
