Synthesis and characterization of conducting polypyrrole-cis-1,4-polybutadiene composites

, 1998
Conducting composite films of cis-1,4-polybutadiene with polypyrrole were prepared electrochemically. Polymerization of pyrrole was carried on cis-1,4-polybutadiene-coated platinum electrodes.

KINETIC STUDIES ON THE FORMATION OF POLYBUTADIENE

, 1948
The growth rate of polybutadiene 'popcorn' is essentially the same in butadiene liquid and vapor, is proportional to the initial weight of seed used, and increases with increased active oxygen content of the seed and with increased temperature.

Field-cycling nuclear magnetic resonance relaxometry of thermoreversible polybutadiene networks

, 2020
Chain dynamics in thermoreversible polybutadiene networks were studied in comparison to linear polybutadiene using field-cycling NMR (nuclear magnetic resonance) relaxometry. The effect of rapidly fluctuating cross links on the chain mode relaxation time

Analysis of mechanisms of rotational motion of polybutadiene macromolecules

, 2020
Times of spin-lattice, spin-spin and effective relaxations in the MW-4 sequence averaging dipole interaction have been measured in the temperature range 170-320°K for eight polybutadiene specimens with MW in the range 103-106.

AMMONIUM PERCHLORATE AND AMMONIUM PERCHLORATE- HYDROXYL TERMINATED POLYBUTADIENE SIMULATED COMBUSTION DOI 10.5028/jatm.2012.04014811

Journal of Aerospace Technology and Management, 2012
The combustion simulation of ammonium perchlorate was carried out with the software Chemkin, in two steps: the burning behavior of pure ammonium perchlorate and the one of formulated ammonium perchlorate with hydroxyl terminated polybutadiene binder.
