Hard segment model compounds based on diphenyl methane diisocyanate (MDI) and hydroquinone bis(2-hydroxyethyl) ether (HQE) were synthesized; these models were end-capped with ethanol (E) or 2-phenoxyethanol (F). NMR spectroscopy and GPC analysis confirm the expected structure: R-(MDI-HQE) pฯช1 -MDI-R

## Abstract Novel poly(ethylene ether carbonate) polyurethane elastomers (PECโ€PUE) based on methylene diphenyl diisocyanate (MDI) and poly(ethylene ether carbonate) diol (PEC) were prepared and characterized. The diol PEC was a new material obtained by copolymerization of ethylene oxide and CO~2~ i
