## Abstract The behavior of the molecular motions of nine synthetic polybutadienes, two synthetic polyisoprenes, and an ethyleneβpropylene copolymer were studied by proton magnetic resonance absorption. The values of the line widths and the second moments were estimated as a function of temperature
