These results are in good agreement with activation energies of the same small molecules in similar polyurethanes [30].

Moreover, thermoplastic polyurethanes are suitable for in-situ reaction during melt blending.
Polyurethanes are applied in many sectors of the economy, and primarily in the construction sector, foundries, footwear, automobile, aeronautical, and shipbuilding industries, and as insulating material for manufacturing of household appliances.
The complex will be able to crack a wide range of feedstocks and produce
polyurethans, propylene oxide, propylene glycol, elastomers, polyethylene, glycol ethers and amines, the company said.
From a formulation perspective,
polyurethanes offer an opportunity to design in scratch recovery.
The object of our work is the synthesis of new raw materials for the production of specialty polyurethanes plastics.
Our work was directed to a modified solvolysis procedure which enables us to produce new polyols from polyurethane soft foams which, according to the aim mentioned above, can be processed to high-grade polyurethanes, especially coatings, adhesives and sealants as well as composites, by formulation with polyisocyanates.

polyurethans. Cancer Res 35:1591-1596 (1975).
It is known that the viscosity increase in time for reactive
polyurethanes is very sensitive to the quality of the reactant mixture.
