  abstract = {Dielectric measurements of 4,4'-methylenebis (N,N-diglicydilaniline)
	(MBDGA) have been carried out along both pressure and temperature
	pathways. The phenomenon of decoupling between the DC-conductivity
	and the structural (alpha-) relaxation time has been studied. We
	found that the exponent s in the fractional Debye-Stokes-Einstein
	relation is both temperature and pressure independent, and its value
	can be determined from the ratio of activation volumes for the DC-conductivity
	relaxation and the structural relaxation process, respectively.
	The results for MBDGA have been compared with results previously
	obtained for similar epoxies, i.e., N,N-diglycidylaniline and N,N-diglycidyl-4-glycidyloxyaniline.
	A correlation between the molecular size and the fractional exponent
	has been established.},
