Polycyclooctene-polylactide triblock copolymer synthesis and subsequent processing via solvent casting, polylactide etching, and plasma etching to yield tunable and tough nanoporous membranes with high surface porosities and hydrophilic properties.
Cyclic polymers, lacking chain ends and featuring unique topological constraints, offer distinctive mechanical behaviors.
Disulfide-containing polyolefins were synthesized by ring-opening metathesis polymerization (ROMP) of the 6-membered disulfide-containing cyclic olefin, 3,6-dihydro-1,2-dithiine, which was prepared by ring-closing metathesis of diallyl disulfide.
The study clearly showed that PAH exposure could damage hematological parameters and blood lipids, and benzene exposure could increase blood pressure, and decrease PLT count.
A stereoretentive catalytic ring-opening metathesis polymerization delivers well-controlled telechelic all-cis polycyclooctene for the synthesis of polylactide-based ABA triblock copolymers.
