Hydrocarbon solutions of polybutadiene, polyisoprene, and polystyrene may be converted into emulsions. The hydrocarbon solvent may then be removed by distillation. The molecular weight of the polymer controls the particle size of its emulsion. An inc

SAN-copolyester TPE graft polyblends could be prepared by solution polymerization initiated by peroxide. The resins lose toughness outdoors and in the UV chamber as evidenced by dramatic decreases in short periods of time in ultimate tensile strength

Rubbers containing a low level of unsaturation such as EPT may be metalated with a chelate made from s-butyllithium and N,N,N′- N′ -tetramethylethylethylenediamine. The lithiated polymers, reacted with styrene, result in polystyrene graft copolym
