Polyurethane Elastomers Modified with Hydroxyethyl-Substituted Ureas

Abstract

One of the most important problems in the chemistry of polymers is establishing the mutual link between their chemical composition, structure and physical properties. Solving this problem will enable polymers with set operational properties to be created. New polymer materials with improved properties may be produced either through synthesis of new monomer and oligomer constituents, or by modifying polymers using various reactive additions [1,2]. The aim of this work was to study the impact of the content and structure of hydroxyethylsubstituted ureas, which are of considerable interest in polyurethane chemistry [3,4], on the macroscopic properties of industrial urethane elastomers.

Synthesis and Characterization of Polyurethane Elastomers

“…Meanwhile, thermodynamic incompatibility between hard and soft segments can lead to the micro-phase separation and hence make a significant contribution. Therefore, soft segments provide the basis of elasticity while hard segments play a role in reinforcing filler and physical crosslinking [1][2][3][4]. In a condensed structure, hard segments usually exist in glassy state or crystalline state.…”
