ABSTRACT:
In a mechanical cell for blending elastomer particles and solution into uniform mixtures, a solid core with an entrance surface, an exit surface spaced apart from and substantially parallel to the entrance surface, and a plurality of minute core passageways therebetween for flow of an elastomer-containing hydrocarbon solution from the entrance surface to the exit surface, the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer to small particles distributed evenly in liquid hydrocarbon solution without plugging the passageways. Typically the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer selected from the group consisting of natural rubber, styrene-butadiene rubber, polybutadiene rubber, polyisoprene, a nitrile rubber, and a copolymer of a 1,4-conjugated diene and a vinyl aromatic monomer, to small particles distributed evenly in liquid hydrocarbon solution comprising a vinyl aromatic monomer. Preferably the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer to small particles having diameters in a range downward from about 200 micrometers.
