Quantitative structure− property relationships (QSPR) are developed to correlate glass
transition temperatures and chemical structure. Both monomer and repeat unit structures are …

Modern technologies demand the development of new glasses with unusual properties.
Most of the previous developments occurred by slow, expensive trial-and-error approaches …

A series of linear non-isocyanate polyhydroxyurethanes (NIPUs) were synthesized by
aminolysis of a PPO bis-cyclic carbonate with two diamines, one of which …

For styrenic random copolymers, the glass transition temperature, Tg, is an important
thermophysical parameter, which is sometimes difficult to measure and determine by …

Polyimide substrates used in flexible display devices need to withstand very high
temperatures and be highly thermally stable. The discovery of polyimides that satisfy these …

The long-term confusing glass transition temperature, T g, and specific heat capacity, Δ Cp,
of the 4, 4 '-diisocyanatodiphenylmethane (MDI) and 1, 4-butanediol (BD) hard segment in …

Structural and morphological interplay between hard and soft phases determine the bulk
properties of thermoplastic polyurethanes. Commonly employed techniques rely on different …

Two main issues are essential nowadays for practitioners in the field of polymeric materials:
how a polymer will behave under dynamic loading conditions and for how long a polymer is …

Polyurethanes are one of the most versatile families of polymers and are one of the most
widely used in thermosets. Due to their static cross-linked structure, they have limited …

Thermotropic polyurethanes with mesogenic groups in side chains were prepared from two
diisocyanates and four diols with stoichiometric ratios of reactive isocyanate (NCO) and …
