The research group of Professor Chengzhong Zong of the Youth Science University has made the latest progress in the study of the formation of the microstructure of thermoplastic polyurethane

Thermal plastic of poly amino ester ( T P the U- ) owner has unique Laid the micro concept junction structure , which is formed into a source to a micro -phase sub- isolated , and micro- phase mixed together
.

This two Species phase interaction for use in the present substance is thermally force learning without phase content and the hydrogen bond for use , which inHydrogen bond as a production raw significantly significant shadow ring

Tsing Island Branch Technology large science cases to the teaching timing group teams in research studies without different junction structure the soft segment of the lead into the pair in T P the U- Micro View junction structure of Movies impact side surface taken to obtain new the intake development , probe cable of the solid given hard segment containing an amount of the situation conditions at , containingThe carbonyl group of the poly hexyl inner esters of two alcohols ( P C L ) , and containing an ether bond in the poly four hydrogen furosemide pyran two alcohol ( P T M G ) on to the end hydroxyl groups of poly but- two -ene ( H T P B ) group T P U of micro concept junction structure and macro concept of energyThe shadow ring

FIG.

1 is in P T M G modified exemplary T P the U- of trans be as Example show illustrating the anti be through processes and sub- sub- mode type

Hydrogen bond is formed as the main to be the hard segment on the - N H and the hard segment on the = C = O and a soft segment on the = C = O or - C - O - C - of between formed into
.

And the hydrogen bond is formed into will then be turned induced by the peak ofSplit points

P C L to at H T P B group T P the U- of modified properties will increase the large micro- phase mixed together , but the H T P B of the phase content of for weaker in P T M G
.

P C L pro make T P the U- shaped as feet inches and more smaller , sub- cloth more addedThey are uniform in the hard segment junction crystal , but the junction crystallization degree than the lower

P T M G and P C L is introduced into not only be of H T P B group T P the U- of micro concept junction structure produced green shadow ring , and and will on the macro concept of energy producing raw shadow ring
.

In the force learning of energy on , P C L on to pull stretching strongDegree and breaking crack extension length of the lifting liter as a relatively good , mention liter after the force learning properties can few almost be to match the United States pure P C L group T P the U-
