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: 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 second monomer alternating 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 shrink film packaging applications.

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

Abstract: A mixture if a carboxylic acid and an alkali metal carboxylatecoating rubber in a vinyl monomer is provided, The resulting composition has a relatively low viscosity and is particularly adapted for preparing a thermosettable composition suitable for preparing reinforced plastic articles by combining an unsaturated polyester, the alkali metal carboxylate-containing rubber solution containing the carboxylic acid, a catalyst, and a reinforcing agent. The resulting composition when cured exhibits high impact and good surface finish.
