Polyurethane elastomers (PUEs) containing trans-1,4-bis(isocyanatomethyl)cyclohexane (1,4-H6XDI) have been synthesized by polymerizing 1,4-H6XDI with poly(oxytetramethylene) glycol and 1,4-butanediol. The molecular aggregation state mechanical properties of these PUEs compared those exhibited PUE analogues made MDI diols. hard segment chains in the 1,4-H6XDI-based are found to readily crystallize form strong hydrogen bonds due a high symmetry molecule. Consequently, exhibit well-organized domains. This leads their generally superior as well-known MDI-based PUEs. 1,4-H6XDI's lack aromatic moieties is expected greatly enhance color stability resulting All above features suggest could replace range applications.
