ABSTRACT:
A process for the manufacture of stable interpenetrating polymer blend networks is provided, comprising the preparation of a gel of a poly(alkylene) polymer by dissolving it in a mixture of one or more organic solvents and one or more vinyl aromatic monomers, optionally mixed with a compatible monomer, cooling this solution to a temperature of at most 80.degree. C., adding of a radical forming initiator for the polymerization of the vinyl aromatic monomer(s), homogenizig the solution, cooling the solution to a temperature to obtain gelation of the polyalkylene polymer in the solvent mixture, followed by heating the obtained gel to a temperature of at least 80.degree. C. and subsequently polymerization of the vinyl aromatic monomer(s) in bulk or suspending the heated solution in a vigorously stirred aqueous medium of a lower temperature to obtain gelation and polymerizing the suspended gel into polymer blend beads, stable interpenetrating polymer blend networks and intermediate gel used therewith.
