Viscometry Constants for 1,4 Polybutadiene in Tetralin at 135C

Abstract

During the course of a research program on blends of crystallizable polybutadiene (PBD) isomers, we needed to determine the molecular weight of a trans 1,4 polybutadiene sample. Gel Permeation Chromatography (GPC) of the trans 1,4 PBD in 140 C tetralin was unsuccessful due to extensive polymer degradation during testing. Therefore, we obtained Mark-Houwink constants for a series of 1, 4 PBD (mixed cis/trans) standards of known molecular weight and low polydispersities. The constants were determined using solutions of PBD in tetralin at 135 C, and then we obtained the Mv of the trans 1,4 PBD sample.
