Abstract
A primordial net bosonic charge is introduced in the context of the bulk-viscosity-driven inflationary models. The analysis is carried through a macroscopic point of view in the framework of the casual thermodynamic theory. The conditions for having exponential and generalized inflation are obtained. A phenomenological expression for the bulk-viscosity coefficient is also derived.Keywords
