Crystallization and Melting Behavior of 1,2 Syndiotactic Polybutadiene

, 2004
1,2-Syndiotactic polybutadiene was synthesized at -30degreesC using the catalyst system CrCl(dmpe)(2)-MAO. The syndiotactic index of the butadiene sequences, expressed as a percentage of syndiotactic pentads [rrrr], was evaluated by C-13-NMR measurements.

Synthesis of a-and a-norbornenyl-polybutadiene macromonomers and their ring-opening metathesis polymerization

, 1998
Norbornene-ended polybutadiene (PBu) macromonomers have been prepared via two different routes: a-norbornenyl-polybutadiene was derived from a norbornene-containing carbanionic initiator, whereas w-norbornenyl samples were obtained through deactivation ...

Clustering and nanoscale vitrimeric behavior in telechelic polybutadiene model vitrimers

Despite the promise of vitrimeric materials applications, there are many aspects that remain poorly understood. To advance the fundamental knowledge of these materials, model systems of well-controlled composition are needed. Here we report the synthesis
