Abstract: A copolymer is prepd. in a reaction zone by: (a) introducing a monovinylaromatic monomer and an initiator in the presence of a randomiser and polymerising until no free monomer is present; (b) adding an initiator and a monovinylaromatic monomer and polymerising until no free monomer is present; (c) adding a mixt. of monovinylaromatic monomer and conjugated diene and polymerising until no free monomer is present; (d) adding a mixt. of monovinylaromatic monomer and conjugated diene monomer and polymerising until no free monomer is present; (e) adding a conjugated diene monomer and allowing complete polymerisation to occur until no free monomer is present; and (f) adding a coupling agent. Only two initiator charges are present and are added in steps (a) and (b). Also claimed are (i) polymodal copolymers produced by the method; (ii)-articles made from the copolymers, and (ii) a polymodal coupled block copolymer having chains resulting from coupling; S-S-B/S-B/S-B-Li S-B/S-B/S-B-Li S = monovinyl aromatic block; B = conjugated diene block; B/S = tapered B and S block; and Li = living polymer or coupling site.

Abstract: Nitrogen-containing copolymers are prepared by the reaction of lithiated hydrogenated conjugated diene-monovinylarene copolymers with nitrogen-containing organic compounds. The nitrogen-containing copolymers are oil additives which combine the aspects of viscosity index improvers with dispersant properties.

Abstract: A method of preparing a polymer under solution polymerization conditions in a reaction zone comprising: (a) charging a monovinylaromatic monomer and an initiator in the presence of a randomizer; thereafter (b) charging an initiator and a monovinylaromatic monomer; thereafter (c) charging a mixture of a monovinylaromatic monomer and conjugated diene monomer; thereafter (d) optionally charging a mixture of monovinylaromatic monomer and conjugated diene monomer; and thereafter (e) charging the reaction mixture with a coupling agent, wherein in each of steps (a) and (d) polymerization is conducted until essentially no free monomer is present.

Abstract: A method for preparing tapered block copolymers in a polymerization process by sequentially charging: (1) an initiator and monovinylaromatic monomer in the presence of a randomizer; (2) an initiator and monovinylaromatic monomer; (3) a mixture of monovinylaromatic and conjugated diene monomers; (4) a mixture of monovinylaromatic and conjugated diene monomers; (5) conjugated diene monomer; and (6) a coupling agent; and the polymodal tapered block copolymers prepared thereby. The copolymers are particularly useful neat or in blends for applications such as packaging and food or drink containers which require transparency and good environmental stress crack resistance.

Abstract: A method for preparing tapered block copolymers in a polymerization process by charging an initiator and monomers sequentially with one or more charges of first one of the monomers, then with a mixture of the two monomers, and then with one or more charges of the first monomer to produce a polymodal tapered block copolymer. Suitable monomers include conjugated dienes and monovinylaromatic compounds. The copolymers are particularly useful for applications requiring environmental stress crack resistance.
