Copolymerization of ethylene with styrene catalyzed by a linked bis(phenolato) titanium catalyst

, 2006
Copolymerization of ethylene with styrene, catalyzed by 1,4-dithiabutanediyl-linked bis(phenolato) titanium complex and methylaluminoxane, produced exclusively ethylene-styrene copolymers with high activity. Copolymerization parameters were calculated to

Alternating Copolymerization of Cyclohexene Oxide with Carbon Dioxide Catalyzed by (salalen)CrCl Complexes

, 2016
Copolymerization of cyclohexene oxide with carbon dioxide was investigated by using chromium complexes with salalen ligands which are reduced analogues of salen ones (salen-H2 = N,N′-disalicylidene-1,2-ethylenediamine).

Alternating Copolymers by Complexed Copolymerization

, 1973
There have been few studies on how the nature of copolymers is affected by their sequential structure. This is because, in the past, the sequential structure of most copolymers could not be controlled at will.

“Schizomorphic” Emulsion Copolymerization Particles

Macromolecular Rapid Communications, 2011
AbstractCryo‐electron microscopy, atomic force microscopy, and light microscopy investigations provide experimental evidence that amphiphilic emulsion copolymerization particles change their morphology in dependence on concentration. The shape of the particles is spherical at solids content above 1%, but it changes to rod‐like, ring‐like, and web‐like ...

Copolymerization propene non-conjugated dienes: derivatization through hydroboration and epoxidation

, 1992
International audienceThe approach described in this paper involved copolymerization of propene with a non conjugated diene so that only one of the two double bonds is incorporated by copolymerization; the second double bond may then be further engaged ...
