Özet

Development of new polyurethanes (PUs) and the modification of the existing ones are still considered as novel areas. This research deals with the preparation of PUs synthesized from its starting materials (without using any solvent, catalyst or chain extender) and examination of the structure property relation through different techniques. Series of segmented elastomeric PU films were synthesized by using different combinations of toluene diisocyanate (TDI) and polyol(polyoxypropylene/polyoxyethylene triol) without using any other ingredients and by one-shot polymerization method. The chemical, thermal and mechanical properties were examined for 2D PU films and the effects of preparation parameters on the structure-property relations were discussed in detail.
