Patent abstract

Polymer particles of ultrahigh molecular weight poly(alpha-olefins) may be made stable toward agglomeration by suspension within a co-suspension of self-dispersing waxes. This combination prevents polymer agglomeration over time while maintaining good flowability properties. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, may be shipped and stored for extended periods of time without irreversible loss of the suspension stability.
