Zhang, Xixiang published the artcileEffect of the lanthanum and cerium phenylphosphonates on the crystallization and mechanical properties of isotactic polypropylene, Recommanded Product: Tris(2,4-di-tert-butylphenyl) phosphite, the publication is Journal of Polymer Research (2021), 28(4), 124, database is CAplus.
In this article, the lanthanum phenylphosphonates (LaPPA2) and cerium phenylphosphonates (CePPA2) were synthesized and the effect on the crystallization conducts and mech. performances of isotactic polypropylene (iPP) were studied. After adding 0.05wt.% of LaPPA2 and CePPA2, the crystallization temperature enhanced appreciably. The polarized optical microscopy (POM) imagines indicated that the LaPPA2 and CePPA2 could accelerate the crystallization speed and reduce the spherulites sizes significantly. The presence of LaPPA2 and CePPA2 decreased appreciably the non-isothermal crystallization kinetics parameter F(T). Meanwhile, the nucleation efficiency of LaPPA2 and CePPA2 was similar to industrial standard NAs NA-11, HPN20E and HPN68L. In addition, the mech. properties of iPP have been improved by adding LaPPA2 and CePPA2. According to the investigation of nucleated iPP viscoelasticity, it can be confirmed that the CH/π interplay between iPP and the aromatic groups of LaPPA2 and CePPA2 promoted the attachment of iPP helix and following nucleation.
