Influence of Electrostatic Interactions and Hydrogen Bonding on the Thermal and Mechanical Properties of Step-Growth Polymers
… polyurethanes containing either a novel phosphonium diol or 1,4-butanediol chain extenders were prepared using a prepolymer method. The novel phosphonium polyurethane was more crystalline, and it was presumed that hydrogen bonding in the non-charged polyurethane restricted polymer …
