Synthetic method of polyethylene-poly(methylmethacrylate) (PE-PMMA) polymer hybrid via reversible addition-fragmentation chain transfer (RAFT) polymerization with functionalized polyethylene

SummaryPolyethylene-poly(methylmethacrylate) (PE-PMMA) polymer hybrid was synthesized via RAFT polymerization of MMA with PE chain transfer agent (PE-CTA) for the first time. The structure of PE-CTA produced by sequential functionalization of terminally hydroxylated PE was confirmed by 1H NMR and FT...

Zusammenfassung:SummaryPolyethylene-poly(methylmethacrylate) (PE-PMMA) polymer hybrid was synthesized via RAFT polymerization of MMA with PE chain transfer agent (PE-CTA) for the first time. The structure of PE-CTA produced by sequential functionalization of terminally hydroxylated PE was confirmed by 1H NMR and FT-IR analyses. The results of GPC after MMA polymerization revealed that the molecular weight (Mw) of the resulting polymers increased compared with the one of the PE-CTA. 1H NMR analysis of resulting polymers confirmed that the amounts of PMMA segments were in a range of 7.8 and 23 wt %. TEM images indicated the nanometer level microphase-separation morphology between the PE segment and PMMA segment.
