“…The spectra of ZnSA shows peaks of stretching vibrations of COO − at 1598 cm −1 , 1536 cm −1 (asymmetric stretching vibration), 1466 cm −1 and 1398 cm −1 (symmetrical stretching vibration). It is consistent with the description in the literature [32,33]. The results of FITR spectra indicate the successful synthesis of ZnSA.…”

“…However, when the cooling rate exceeds 40 °C•s −1 , the mesophase is not formed in the 0.2wt% ZnSA/PPR, which suggests that ZnSA provides nucleation sites during the crystallization and thus preventing the appearance of mesophase during rapid cooling process to some extent. [26,33]. The peaks of all samples gradually become low as the cooling rate increases.…”

“…Additionally, the compatibility between inorganic fillers and polybutene is poor so the content of added inorganic fillers was relatively high which was usually about 3-7wt% [42,47]. Carboxylic acid metal salts show a great nucleating efficiency on PP [48][49][50][51][52] but few of their effects on PB were investigated. Therefore, a study about the effect of carboxylic acid metal salt NA on the crystallization and crystal transformation behavior is very significant.…”

“…[13,14] While the 𝛽-iPP is metastable and can occur only under pressure. [15,16] Also, the 𝛽-form is favored by the presence of a temperature gradient, [14,17] a flow field, [17,18] or by adding a nucleating agent during crystallization. [19,20] The 𝛾-iPP is favored during crystallization under elevated pressure or when the isotactic sequence length is interrupted.…”
