| Abstract: | The thermostimulated creep of two series of amorphous polyolefins, (CH2)mC(CH3)2 and (CH2)mC(CH3)(CH2CH3) where m = 1, 2 and 3, was investigated from 77 to 350 K. The broad relaxation process observed around the glass transition in each polyolefin can be described by a distributed retardation time τ obeying a compensation law where τc and Tc are characteristic of the polyolefin. |
