The ethylene-propylene copolymers with various monomer ratio have been synthesized by using titanium catalyst. The composition
monomer sequence distribution
molecular weight and crystallinity for the copolymers were determined. The side group-SO2Cl was introduced to ethylene-propylene backbones through chlorosulfonation with SO2Cl2. Effects pf initiator and sulfuryl chloride agent on sulfonation in chlorosulfonated products were investigated. Structural analysis of the chlorosulfonated copolymer by 13C-NMR has shown that hydrogens on CH3 could be substituted by a -SO2CI group while those on CH2 substituted by either -SO2CI or -Cl group
but those on CH substituted by neither pendant groups.
