摘要

Abstract

A series of non-isocyanate linear high molecular weight poly(ester urethane)s (PETUs) were prepared through an environmentally-friendly route based on dimethyl carbonate

6-hexanediol and 1

6-hexanediamine. In this route

the polyurethane diol was first prepared by the reaction between bis-1

6-hexamethylencarbamate (BHC) and 1

6-hexanediol. A series of polyester soft segments of polyurethane have been synthesized from the polycondensation of adipic acid and different diols

including butanediol

hexanediol

octanediol and decanediol. The subsequent polycondensation of polyurethane diol and polyester diol led to linear PETUs. The resultant polymers were characterized by GPC

FTIR

H-NMR

C-NMR

DSC

WAXD

TGA and tensile test. The results indicated that PETUs possess weight-average molecular weights higher than 1×10

and the tensile strength as high as 10 MPa. The thermal properties

crystallization behavior

microphase separation behavior and morphology were studied by DSC and AFM

and the results indicated that the degree of phase separation was affected by two factors

the crystallization and hydrogen bonding interaction between soft segment and hard segment.
