The effects of the inclusion of 1,2,4-triazole derivatives into the main chains of the polyurethane urea exposed to UV radiation
Autor: Stefan Oprea, Violeta Otilia Potolinca
Publikováno v: High Performance Polymers. 34:115-128
Linear polyurethane urea containing 1,2,4-triazole segments was obtained by polyaddition of the 3,5-diamino-1,2,4-triazole (DATA) to urethane prepolymer. Also, three crosslinked polymers with different crosslinkers (2,4,6-triaminopyrimidine (TAP), gl

Structure–properties relationship of the polyurethanes that contain Schiff base in the main chain
Autor: Stefan Oprea, Veronica Oprea, Livia Ingrid Diaconu, Violeta Otilia Potolinca
Publikováno v: High Performance Polymers. 32:784-792
This article studies the diversification of useful properties of polyurethane (PU) structures by the inclusion of new components. PUs containing a Schiff base in the main chain were synthesized by using N, N′-bis(salicylidene)-1,3-propanediamine as
