A heterobifunctional monomer, namely, 3-(4-ethenylphenyl)-3,4-dihydro-2H-1,3-benzoxazine (VBOZN), which contains both vinyl group and benzoxazine group, was successfully prepared by three-step method with high purity and satisfactory yield. The chemical structure of VBOZN was identified by NMR, FTIR and elemental analysis. VBOZN selectively underwent free radical polymerization initiated by azodiisobutyronitrile...
Two series of alkylamine-modified (oleylamine and octadecylamine) styrene-butadiene rubber (SBR)/graphene oxide (GO) composites were fabricated through a facile green method involving co-coagulation and in-situ interfacial modification techniques. Both alkylamines were shown to graft onto the GO surface via covalent and ionic-bonding, and GO was partially reduced into graphene during alkylation. The...
Amphiphilic triblock terpolymers, poly(n-hexyl isocyanate)-b-poly(ethylene glycol)-b-poly(n-hexyl isocyanate) (defined as PHIC-b-PEG-b-PHIC) was synthesized by using CpTiCl 2 –PEG–CpTiCl 2 as macromolecular initiator. GPC, FT-IR, 1 H NMR and DSC analyses confirmed the formation of amphiphilic block terpolymers. UV–vis spectra demonstrated that the PHIC block in the triblock...
