Acrylonitrile Copolymerizations. IV. Butadiene Copolymerization

Rubber Chemistry and Technology, 1971
Abstract The kinetics of the acrylonitrile-butadiene radical copolymerization, carried out in solution at 60° C, have been followed using gas chromatographic analysis. Remote unit effects are observed only on the butadiene-ended radicals, but they seem to involve a quite long sequence of butadiene units.

Copolymerization

Journal of Applied Chemistry, 1951
AbstractThe mechanism of the copolymerization of two components in addition‐polymerization has been examined in detail for the systems styrene‐methyl methacrylate, styrene‐butyl acrylate, and styrene‐p‐methoxystyrene. In such reactions nine elementary‐radical processes are involved.

On the Melting of Copolymeric DNA

The Journal of Chemical Physics, 1966
A model for DNA molecules is introduced and treated by the methods of statistical mechanics. This model takes into account the difference in bonding free energy between adenine—thymine and guanine—cytosine base pairs. The model used is an extension of the Zimm—Bragg model for polypeptides.

Copolymerization of styrene. V. Copolymerization with α‐cyanocinnamamide

Journal of Polymer Science: Polymer Chemistry Edition, 1974
AbstractCopolymers of styrene with α‐cyanocinnamamide were prepared by free radical initiation in bulk and in DMF solution and also by thermal initiation in bulk. The copolymerization parameters were determined by the conventional scheme of copolymerization and by an improved scheme taking into account the penultimate unit.

Copolymerization of the pair maleic anhydride–dicyclopentadiene: I. Copolymerization and post‐copolymerization at high conversion

Polymer International, 2004
AbstractThe present study describes the kinetic investigation of the complex binary copolymerization system maleic anhydride (MA)—dicyclopentadiene (DCPD). All syntheses were carried out in homogeneous solution; high conversions in soluble and linear copolymer are achievable when starting from an equimolecular monomer feed.

Copolymerization of acrylonitrile. III. Copolymerization with α‐cyanocinnamamide

Journal of Polymer Science: Polymer Chemistry Edition, 1974
AbstractAcrylonitrile was copolymerized in solution with α‐cyanocinnamamide up to low conversions. The conventional scheme of copolymerization fitted this copolymer. The basic properties, such as solubility, viscosity, and thermal behavior, of the copolymer prepared in bulk and in solution were determined.
