New Polyurethanes with a polyurea matrix

Title:
New Polyurethanes with a polyurea matrix
Abstract:
Based on a previously published (Peshkov 2011) synthesis route of nanoscale oligourea dispersion polyols (NODP) a new type of polyurethanes with a polyurea matrix was developed. Polyurethanes with high hardness and elasticity were prepared by reacting a formulation based on the NODP’s and di- or polyisocyanates. The polyurethanes obtained as films were characterised by mechanical tests and dynamic mechanical analysis (DMA). The phase structure depends on the amount of nanoparticles present, the isocyanate index, and the mode of curing. It is suggested that nanoparticles have to be of similar size as the matrix into which they are embedded to show a typical nano- effect such as shown here. These elastic polymers show an unusual high Shore D hardness of some 70 and tensile strength up to 47 MPa at elongations at break of 7 %.
