Polyurethanes are a well-established part of adhesive markets. However due to the toxicity
of di-isocyanates used in the synthesis, finding an alternative route to synthetize …

Abstract A polyurethane/polyhydroxyurethane (PU/PHU) hybrid polymer was synthesized by
reaction of a cyclic-carbonate-terminated prepolymer with triethylenetetramine without …

Polyurethanes (PUs) are a significant group of polymeric materials that, due to their
outstanding mechanical, chemical, and physical properties, are used in a wide range of …

A series of poly (hydroxyurethane)(PHU) materials were synthesized by step growth
polymerization of cyclic carbonates and diamines. Trimethylolpropane tris-carbonate and …

The preparation of non‐isocyanate polyurethanes (NIPUs) by polyaddition of (poly) cyclic
carbonates to (poly) amines represents one of the most optimistic alternatives for replacing …

Non-isocyanate polyurethanes (NIPUs) are a class of polymers prepared by isocyanate free
method. The process of formation of hydroxyurethanes based on cyclic carbonate–amine …

Nonisocyanate polyurethane materials with pending alcohol groups in the polymeric chain
were synthesized by polyaddition reaction of bis (cyclic carbonates) onto diamines. For the …
