ABSTRACT:
The invention pertains to particulate compositions comprising a mixture of a low melting point petroleum additive and a higher melting point polymer which mixture is then coated with a high melting point polymer. The mixture of the additive and higher melting point polymer has a melting point close to the melting point of the polymer (i.e., significantly higher than the melting point of the additive). The high melting point polymer coating allows the composition to be added to petroleum systems having high temperatures without immediately dissolving, i.e., the compositions are only slowly soluble in hot crude oil. Accordingly, a slow, controlled release is afforded by the compositions of the invention.
