Claim:
1. A method of servicing a well bore comprising: providing a treatment fluid comprising a carrier fluid and temperature-activated polymeric particulates, wherein the temperature-activated polymeric particulates comprise at least one polymeric material selected from the group consisting of polystyrene, styrene-butadiene copolymers, polyfluorostyrene, polychlorostyrene, polydichlorostyrene, and polybromostyrene; and introducing the treatment fluid into a well bore annulus, wherein the temperature activated particulates have a selected glass transition temperature and wall thickness such that the temperature activated particulates withstand an initial temperature and pressure during an initial placement of the temperature-activated particulates into the well bore annulus such that the temperature-activated particulates maintain at least about 95% of their initial volume during the initial placement, wherein the initial volume is the volume of the temperature-activated particulates prior to the introducing; wherein the wall thickness is in a range from about 100 microns to about 1 millimeter.
