Functional polymers. L.: Terpolymers of 10-undecenoate derivatives with ethylene and propylene

Abstract Terpolymers of 2,6-dimethylphenyl 10-undecenoate with ethylene and propylene have been synthesized. With titanium-based coordination initiator systems, a crystalline terpolymer was obtained which consists of blocks of ethylene and propylene, indicated by two distinct melting transitions. With vanadium-based systems, an amorphous ethylene/ propylene terpolymer was obtained. The crystalline terpolymer was hydrolyzed to the sodium carboxylate salt, which was acidified to give the polymeric carboxylic acid. All polymers were characterized by their infrared,1H-, and 13C-NMR spectra, by differential scanning caiorim-etry, elemental analysis, and dilute-solution viscometry. In addition the polymeric sodium salt was characterized by wide-angle x-ray diffraction.
