intrinsic strength
3.High molecular weight biodegradable poly(hexane-succinate) was synthesized by direct polycondensation from succinic acid and 1,6-hexanediol,the chemical structure was identified by FTIR and ~1H-NMR,the intrinsic viscosity was measured by Ubbelohde viscometer,the melting point was determined by DSC,and the tensile strength was 30.9MPa,the elongation at break was 869.5%,in the synthesis procedure high molecular weight of product(Mn=46503) was obtained with the yield of 95.5%.
4.This article tries by the isomorphism to say the strength corresponding isomorphism has analyzed two intrinsic uniformities, by moves the sentiment to say "the sentiment" explains it with "the second world" the relation, thus mediates by the isomorphism moves the sentiment to mention proves together "beauty forms in the second world" this view.
