Abstract
Measurements were made on the dynamic mechanical properties of nine po lyetherureas of varying long chain oligomer molecular weight, type of diisocyanate and type of aromatic chain extender. It was found that lo ng chain oligomer influences the degree of phase separation and hence the soft segment glass transition temperature while diisocyanates and chain extender structure affects mainly the behaviour above the glass transition temperature.
