It is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. On this basis, the effect of strongly dimerising ureidopyrimidinone end groups (UPy) with the capability of quadruple hydrogen bonding array formation on the material properties of polycaprolactone/ polyhydrofuran supramolecular polymer blends has been studied. The mechanical test results revealed that the supramolecular strategy resulted in up to 110% and 500% increase in tensile strength and Young's modulus, respectively. Observation of a single glass transition temperature in DSC traces of the blends shows that phase compatibility improved significantly upon blending. http://jips.ippi.ac.ir/article_557_95e91d9c75f47a2fff0ce1dd063c0c08.pdf
