Method of production of polyblends polymers, with the aid of a catalytic system combines a saturated aliphatic acid and salts of hydrates or a of the water, and novel products thus obtained

摘要

This invention relates to an improved process for producing polyblends wherein said process has unexpectedly high rates of polymerization wherein a polymerizable mixture of a monovinylidene aromatic monomer and a diene rubber are partially polymerized en masse through phase inversion with the partially polymerized mixture being suspended in an inert liquid and the polymerization essentially completed; the improvement comprising utilizing a particular catalyst system, in combination with, a saturated aliphatic acid containing 12 to 20 carbon atoms and a compound selected from the group consisting of hydrated salts and water in the mass and suspension polymerization steps of the process. Said catalyst system having a half life of less than one hour at 130 C., and a 10 hour half life at a temperature of 95. degree. to 115 C.
