Of the many permutations available for modifying the properties of the polymers, the incorporation of functional groups into an otherwise nonpolar material is substantial. Hence, olefin copolymers of alpha-olefins with polar monomers with various architectures remain an ultimate goal in polyolefin engineering. This paper deals with the comparison of the copolymn. kinetics of Me acrylate and 1-octene, in free radical polymn. (FRP) and atom transfer radical poymerization (ATRP), using online 1H NMR spectroscopy, that results in accurate information on the copolymn. Preliminary detd. reactivity ratios, indicate that there is excellent agreement between values for FRP and ATRP systems. The copolymers of MA & 1-octene, obtained using FRP, have a lower MM as compared to that for a homopolymer of MA using the same technique. Good correlation of the obsd. molar mass with the theor. ones coupled with low polydispersity, point at ordinary ATRP behavior.
