Abstract: Process for the polymerization of olefins CH 2 -CHR, in which R is hydrogen or a hydrocarbon radical with 1-12 carbon atoms, carried out in the presence of a catalyst component (A) comprising Mg, Ti and halogen as essential elements and of a catalyst component (B) capable to produce, under the same polymerization conditions, a polymer with an average particle size lower than that obtainable with the said catalyst component A. The said process provides polymers with increased bulk density.

Abstract: A method for controlling a chemical reactor such as a gas-phase reactor using a non-linear predictive control includes steps for generating a plurality of signals representing a current state of the chemical reactor and reflecting a respective constituent of reactants in the chemical reactor, calculating a future state of the chemical reactor responsive to said plurality of signals and referenced to mass hold-up of the reactants in the chemical reactor, and controlling at least one parameter related to the chemical reactor so as to control the future state of the chemical reactor. Spurious control events due to noise in sensor or controller output signals are preferably minimized by filtering these signals using a N-sign filter subroutine.

Abstract: The thermal oxidative stability of acrylic grafted polymers is improved by (a) graft polymerizing monomers selected from the group consisting of (i) an ester or salt of an unsubstituted or 1-3 C alkyl-substituted acrylic acid and (ii) an ester or salt of an unsubstituted or 1-3 C alkyl-substituted acrylic acid and about 1 to about 10 mole %, based on the total monomers added, of an unsubstituted or 1-3 C alkyl-substituted acrylic acid, to a backbone of a propylene polymer material in the presence of a 4-vinyl-substituted 5-12 C cyclic 1-alkene, wherein the total amount of polymerized monomer is about 20 to about 200 parts per hundred parts of the propylene polymer material and the vinyl-substituted cyclic alkene is present in an amount of about 1 mole % to about 30 mole %, based on the total moles of monomer added, and (b) removing any unreacted grafting monomer from the resulting grafted propylene polymer material, decomposing any unreacted initiator, and deactivating any residual free radicals in the material, wherein steps (a) and (b) are carried out in a substantially non-oxidizing environment.

Abstract: A compatible blend of an engineering thermoplastic such as a polyamide and an olefin polymer material is prepared by (1) making an oxidized olefin polymer material containing carboxylic acid groups or derivatives thereof, (2) extruding a mixture of (a) the oxidized olefin polymer material from step (1), (b) an engineering thermoplastic, (c) optionally, an inorganic base, and (d) optionally, a non-oxidized olefin polymer material, and (3) recovering a blend of the engineering thermoplastic, the oxidized olefin polymer material or an ionomer thereof, which acts as a compatibilizer, and, optionally, the non-oxidized olefin polymer material. The oxidized olefin polymer material can be made by treating the olefin polymer material with an organic peroxide initiator while adding a controlled amount of oxygen.
