AN INTERMOLECULAR ^(13)C{~1H} NUCLEAR OVERHAUSER EFFECT FOR THE CARBON OF CCl_4 IN POLYMER SOLUTIONS

摘要

An intermolecular 13C{1H} NOE of CCl4 in the solutions of polystyrene and polybutadiene and their copolymers was observed. The results show that the defined polymer-CCl4 interaction variable has a linear relation with the polymer composition and the difference of solubility parameters and exponentially depends on the reciprocal of temperature.
