Catalyzed Polymerization

An analysis of the products of sodium-catalyzed polymerization of butadiene and isoprene in the presence of toluene suggests that initiation of polymerization takes place by the formation of a disodium addend rather than a free radical. The diaddend reacts with toluene to yield butene-2 and sodium benzyl. Since all of the low molecular weight polymers analyzed were shown to conform to the general formula C6H5CH2(monomer)nH, sodium benzyl is considered to be the chief chain initiator. Chain termination took place by reaction with toluene to regenerate the chain carrier, sodium benzyl. The nature of the acids separated on carbonation of a polymerizing system supports this conclusion.

Akway (Drimys piperita Hook f.) was known as an endogenous plant of Indonesia. This plant was investigated as free radical scavenger based on paramagnetic properties. This study aimed to identify the bioactive compound and the role of Fe metals ions to enhance the free radical scavenger capacity as Low molecular weight antioxidant (LWMA) of akway. This study was designed by ultra-performance liquid chromatography (UPLC) coupled with ultra-high-resolution time of flight-mass spectrometry detector (TOF-MS), docking (Pyrex and Discovery Studio 2016 Client) and pharmacokinetic properties prediction (SwissADME). UPLC-TOF-MS analysis showed that herbal akway bark has five molecular formula (C4H3N10O21-, C14H19N4O91-, C4H7N6O51-, C15H28NO31+, and C23H32NO71+). The docking was illustrated the complex binding akway formula with Fe and its role as a metal donor and metal acceptor. It also confirmed on pharmacokinetics properties prediction which molecular compounds of akway have aqueous solubility. It meant the herbal akway bark complexed to Fe could be a low molecular weight antioxidant and it could be escalated free radical scavenger capacity

Maleic anhydride (MA) was polymerized by a free radical mechanism (PMA) and transformed into the poly-acid and its alkali salts, the ionic conductivities of which were determined. Blends of the lithium salt with propylene carbonate (PC), low molecular weight poly(ethyleneglycol) (PEG), and some crown ethers show improved conductivities. Alkali alcoholates and alcohols react with PMA to form linear poly(methylesters), comb-shaped polymers with methoxy poly(ethyleneoxide) pendants, and PEG cross-linked structures. Alkalisalt/ester copolymers as well as LiClO4 podand complexes were studied. Among these, the viscous comb-shaped polymers show the highest conductivities, when having a Li : O ratio of 1:2.7, i.e. x = 10-5S/cm at 20°C and 4 · 10-3S/cm at 80°C.
