In addition to classical organic synthesis, SPS EUROCHIM conducts research in the field of polymer chemistry.
This focus area includes:
- Development of the technology for preparation of highly cross-linked styrene-divinylbenzene microspheres used as a basis for the production of sorbents for high-performance liquid chromatography.
- Development of methods for modification of polymer particles by means of the controlled polymerization RAFT (reversible addition-fragmentation chain-transfer polymerization), ATRP (atom transfer radical polymerization), etc.
Characteristics of polymeric sorbents
Degree of cross-linking: up to 80%.
Polydispersity index in the interval: 1.03 – 1.15.
Size from 2.5 to 3.5 microns.
Gauge pressure – up to 200 atm.
Modification of polymeric sorbents
The developed surface modification methods allow to grow polymers of various chemical nature (hydrophobic, hydrophilic, ion-exchange, optically active) on particle surface.
Hydrophilic surface of particles allows using them for protein separation.
