 Activation energies of relaxation processes

Hello,

I am looking for the activation energies of alpha, alpha(prime), beta
and gamma-peaks of polypropylene,  polyethylene and
ethylene-propylene-{*filter*}.
Until know I only found the activation energies for PP:
alpha peak: 400kJ/mol
alpha(prime)-peak: 110-170kJ/mol
(
my measured values for a three phase polymer
PE-particles, sourrounded by EPR, in a PP-matrix lead to
alpha peak: 665 kJ/mol
alpha(prime)-peak: 133 kJ/mol
)
Any hints, very I can find activation energy data?

Bernd
