Examination of polymerisation possibilities for polyamides, polyester, polycarbonates and biopolymers

The TITK has many decades of experience in industrially established processes for the polymerisation and co-polymerisation of polyamides and polyesters.

The institute’s studies include work on polymerisation of homo and co-polymers on the basis of polyamide6, polyamide66 and polyesters(PET, PEN, PC) as well as analyses that address the incorporation of certain functional additives (submicron and nanoscale materials such as TiO2, ZnO, carbon nanotubes, layered silicates, IR absorbers) during the polymerisation process. Extensive tests of catalysts have been conducted in the past and continue to be carried out on behalf of industrial customers and within the framework of research contracts. The institute has a wealth of experience in in-situ incorporation of reactive and non-reactive flame-retardant monomers into polyamides and polyesters.
