چکیده
|
a series of metal salts of 7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid were synthesized, and their nucleation efficiency in isotactic polypropylene (ipp) was investigated. the results showed that potassium 7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate (obche19) is an effective β-nucleating agent. then, the effect of obche19 concentration on the relative content of β-crystals (kβ) and mechanical properties of ipp was investigated. the results indicated that the maximum kβ reached 0.82 and impact strength increased by 125% compared to that of pure ipp when the content of obche19 is 0.1 mass%. furthermore, the non-isothermal crystallization kinetics and crystallization activation energy were investigated by the caze method and kissinger method, respectively.
