Viscometric Studies of Polybutadiene Based Liquid Rubbers in Benzene and its Derivatives

Abstract

Viscosities of the two liquid rubbers poIybutadiene such as
hydroxyl taminaled polybutadiene (HTPB) and polybulyl acrylonitrile
(PBAN) in four different  organic solvents have been determined
at various temperatures (303-323 K) ovar the concentration
range (0.2-1 %). The temperature and concentration dependences of
Ibe shear viscosity of these systems have been discussed. An equation
that reproduces tile viscosity as a function of temperature and
concentration has been developed. The activation parameters of
viscosity have also been calculated.
