Modification of Epoxy Resin with Polyurethane and Montmorillonite

Anotace

The aim of this doctoral thesis is the chemical and physical modification of brittle epoxy resin (EP) using two different modifiers – polyurethanes and montmorillonite nanoclay – with the purpose to improve its mechanical properties. The use of polyurethanes (PUR) is motivated by the versatility of their structure, which can be easily modulated with appropriate substrates. Those utilized in the thesis were synthesized from polyols (polyethylene glycols and polyoxypropylene diols) with different molecular weights, and two diisocyanates: 2,4-toluene diisocyanate (TDI) and 4,4’-diphenylmethane diisocyanate (MDI).
