Abstract

Abstract

Self-assembly of low molecular weight oligomers possessing good mechanical properties at room temperature and having a low melt viscosity at elevated temperatures are of interest for many applications, such as hot melts and thermoplastic elastomers. Association between end groups can be based on a variety of secondary interactions, such as Vander Waals, hydrophobic, ionic interactions, or hydrogen bonding. A low molecular weight poly (ethylene glycol) (PEG) was functionalized with 2-Ureido-4[1H] pyrimidinone (UPy) functional groups at both ends and their chemical structure as well as the material properties were studied. The chain extension telechelic polymer was characterized by FTIR, 1H NMR spectral studies. The rheological studies revealed that the supramolecular structure of poly (ethylene glycol) is stable upon heating upto 900C. In these polymers, blend with LiClO4 and its conductivity was measured by Electronic impedance spectroscopy. Self-assembly polymers having relatively weak association in combination with crystallization leads to physical cross links, which result in materials with improved properties.
