(9-Anthracenylmethyl)lithium-initiated living anionic polymerization of alkyl methacrylates

Polymerization of Alkyl Acrylates and Alkyl Methacrylates with Starch

A series of C4-C 12 alkyl acrylates and methacrylates was polymerized with starch by irradiating starch-monomer mixtures with 60CO. Homopolymers were extracted with cyclohexane. The amounts of insoluble versus soluble synthetic polymer in polymerizations run with alkyl acrylates varied less with the chain length of the alkyl substituent than in the polymerizations run with alkyl methacrylates: ...

Kinetics of Living Anionic Polymerization of Polystyrenyl Lithium in Cyclohexane

Living anionic polymer chains polymerized with organolithium initiators usually form aggregates through their Li ends in nonpolar solvents. This aggregation structure strongly affects the anionic polymerization (propagation) kinetics. In the conventional molecular picture, the aggregates are assumed to be chemically inert and the propagation occurs only though the dissociated unimers, which lea...

Reactivity of methacrylates in insertion polymerization.

Polymerization of ethylene by complexes [{(P^O)PdMe(L)}] (P^O = κ(2)-(P,O)-2-(2-MeOC(6)H(4))(2)PC(6)H(4)SO(3))) affords homopolyethylene free of any methyl methacrylate (MMA)-derived units, even in the presence of substantial concentrations of MMA. In stoichiometric studies, reactive {(P^O)Pd(Me)L} fragments generated by halide abstraction from [({(P^O)Pd(Me)Cl}μ-Na)(2)] insert MMA in a 1,2- as...
