The effect of CX (alkyl groups) on the migration insertion polymerization (MIP) of PFpCX [PFp = (PPh2(CH2)3Cp)Fe(CO)2] was written by Lo, Ping Hsun;Wang, Xiaosong. And the article was included in Polymer in 2022.COA of Formula: C18H37Cl This article mentions the following:
Migration insertion polymerization (MIP) of organometallic monomers, PFpCX [PFp = (PPh2(CH2)3Cp)Fe(CO)2, CX = (CH2)X-1CH3, X = 12 or 18] was performed under various conditions. The oligomerization occurred in accompany with the monomer cyclization generating PFpCX small rings at the early stage, which was followed by a complete cyclization of the oligomers generating P(PFpCX)n macrocycles. PFpCX small rings could be completely removed via precipitating the crude products in a poor solvent for the macrocycles. The solution and bulk MIP of PFpCX (X = 12 or 18) had a similar cyclization rate but both were significantly accelerated at a higher MIP temperature (100°C). It is explained by the temperature-dependent tendency for the cyclization. The dependence of d.p. (DP) on the MIP conditions was discussed and the self-assembly of resultant P(PFpC12)n was examined In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2COA of Formula: C18H37Cl).
1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.COA of Formula: C18H37Cl
