Synthesis of hybrid block copolymers via integrated ring-opening metathesis polymerization and polymerization of NCA.
Linear hybrid block copolymers with well controlled molecular weights and narrow polydispersities were synthesized via ring-opening metathesis polymerization (ROMP) followed by ring-opening polymerization of amino acid N-carboxyanhydrides.
متن کاملSynthesis of hybrid block copolymers via integrated ring-opening metathesis polymerization and polymerization of NCAw
Hybrid copolymers, which contain segments with distinct structures and properties, are useful materials in various applications such as novel plastics, polymeric catalysis, smart materials, self-assembly, and bionanotechnology. They can be prepared through conjugation of hybrid polymeric segments or polymerization with corresponding initiators. The latter approach is particularly attractive as ...
متن کاملSynthesis and thermal characterization of polymethyl methacrylate
PMMA with molecular mass (PMMA Mw: 1.2×105) was synthesized through AIBN initiated free radical polymerization methyl methacrylate at 100 ± 1°C.The synthesized polymer was characterized through GPC coupled with RI detector in presence of THF as mobile phase at 1.0 mL/ min and simultaneous TG-DTA-DTG in nitrogen. TG data were used to investigate the non-isothermal kinetics of solid-state decompo...
متن کاملCatalytic production of olefin block copolymers via chain shuttling polymerization.
We report a catalytic system that produces olefin block copolymers with alternating semicrystalline and amorphous segments, achieved by varying the ratio of alpha-olefin to ethylene in the two types of blocks. The system uses a chain shuttling agent to transfer growing chains between two distinct catalysts with different monomer selectivities in a single polymerization reactor. The block copoly...
متن کاملSubmicron polyethylene particles from catalytic emulsion polymerization.
Particles of linear polyethylene (M(n) = (2-3) x 10(3) g x mol(-)(1); M(w)/M(n) = 2-4) obtained by catalytic emulsion polymerization of ethylene possess a nonspherical, lentil-like shape with an average aspect ratio of ca. 10 and diameters from 30 to >300 nm, as determined by TEM and AFM. The particle structure results from a stacking of the lamellae along the one shorter axis of the lentils (i...
