Synthesis and characterization of segmented Polyurethanes based on Polyethylene and Polytetramethylene glycols part 2: thermo-mechanical and sweling properties.
Main Article Content
Abstract
In the previous paper [1] we presented our study on the synthesis and
characterization of some SPUs based on polyethylene and polytetramethylene glycols.
Segmented polyurethanes (SPUs) are multiblock copolymers. Due to their specific phase
separation characteristics caused by incompatibility between the hard and soft segments,
they have quite good biocompatibility [2].
In this paper we present the second part of our study on the thermo-mechanicahand
swelling properties of the SPUs based on polyethylene and polytetramethylene glycols. The
effects of the macrodiols on the properties of the SPUs obtained were discussed.
