Abstract

A family of thermoplastic polyurethane blends was synthesized based on the model rigid 4,4-diphenylmethane diisocyanate (MDI) or the novel flexible 4,4’-dibenzyl diisocyanate (DBDI). On employing the ‘one shot’ technique in solution or melt, by selective dissolution in dimethylformamide it obtained polyurethane composites based on two copolymers with a different composition. The materials were characterized by means of dynamic mechanical analysis (DMA)
