The stereoregularity and molecular weight distribution of poly(methylmethacrylate)s prepared with phenylmagnesium bromide or diphenylmagnesium as catalyst in tetrahydrofuran/toluene mixed solvents were investigated in detail. Some of the polymers were fractionated according to molecular weight or by adsorption...
In this study, (2-((1E,2E)-3-phenylallylidene) amino)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile) [referred from here onwards as HCIM that is a highly conjugated imine] was synthesized via a condensation reaction between cinnamaldehyde and a 2-aminothiophene derivative, and subjecte...

Optionally, the second effluent has a higher concentration of the quenching agent than the recycle stream.In another aspect, this disclosure relates to a process for quenching a polymerization reaction using a quenching agent comprising high molecular weight functionalized olefin copolymer. Generally, the...
