Abstract: A graft copolymer is produced by preparing a stable emulsion comprising (a) an elastomer, (b) a solvent for the elastomer of one or more ethylenically unsaturated monomers present in an amount greater than the elastomer, (c) a normally thermoplastic polymer of monomer(s) (b) and, based on the total weight of (a), (b) and (c), 0.05 to 10% of a stabilizer which is a block or graft copolymer of monomer(s) (b) and at least one monomer of the elastomer, and polymerizing monomer(s) (b).  The proportions of (a), (b) and (c) are such that the solution of (a) in monomer(s) (b) forms the discontinuous phase while the solution of polymer (c) in monomer(s) (b) forms the continuous phase.  Monomer(s) (b) is an alkenyl aromatic hydrocarbon or a nuclearly substituted halogen derivative thereof, or a mixture of one of these with methyl methacrylate, acrylonitrile and/or alpha-methyl styrene, or methyl methacrylate alone.  When (b) is styrene, (c) is e.g. polystyrene or a copolymer of styrene and methyl methacrylate or acrylonitrile.  When (a) is polybutadiene and (b) is styrene, the stabilizer may be a graft polymer of styrene or polybutadiene or of butadiene or polystyrene, or of styrene or butadiene on a block copolymer of these monomers, or said block copolymer per se. The emulsions are polymerized in bulk or by dispersion in an aqueous medium.  In Examples 1 and 2 polybutadiene and polystyrene are dissolved in styrene and a graft copolymer of styrene or polybutadiene is added thereto; the resulting emulsion is polymerized in bulk or in an aqueous medium containing di-tert.-butyl peroxide, 2,6-di-ter.-butyl-4-methyl phenol and sodium carboxymethyl methyl cellulose.  In Example 3 a graft copolymer of styrene on a butadiene-styrene copolymer is used.  A graft copolymer of acrylonitrile and styrene on an acrylonitrile-butadiene copolymer is added in Example 4 to a solution of a butadiene-acrylonitrile elastomer and a styrene-acrylonitrile copolymer in a mixture of styrene and acrylonitrile.  The graft coplymer used in Example 5 is of methyl methacrylate on polybutadiene, (a) is polybutadiene, (b) is methyl methacrylate and (c) is polymethyl methacrylate.  In Example 6 the graft copolymer is of styrene and methyl methacrylate on polybutadiene, (a) is polybutadiene, (b) is styrene and methyl methacrylate and (c) is a styrene-methyl methacrylate copolymer.  A block copolymer of styrene and butadiene is used in Example 7 in which (a) is polybutadiene, (b) is styrene and (c) is polystyrene.

The invention is described as applied to an oven in which the conveyer is arranged, constructed, and driven as set forth in Specification 227,575. The trays 20 are provided at one end with projections 26, 27 which, when the tray reaches the end of the lowest run of the conveyer, are received between the screws 3, 4 and guides 25. The screws move the tray outwardly to the point 18, this movement pushing the preceding tray up the guides 21, 22 until its projections 26, 27 engage in the threads of the vertical screws 5, 6. When the latter have raised the tray sufficiently for its rear edge to leave the supporting rails 23, 24, the tray swings into the vertical position to discharge its contents and is carried upwardly in this position until the cams 7, 8 cause its projections to enter lateral guides 9, 10. The tray then slides downwards and is guided by a slope 11 on to a loading platform 13 supported on an eccentrically-mounted rotary drum 12 which is so arranged that, to allow charging, the tray is kept stationary by the raised position of the platform 13 for a short time before being lowered into engagement with the screws 1, 2. The latter carry the loaded tray into the oven, there being provided spaced supports 14, 15 from which the tray is removed by one of the pivoted carriers of the oven conveyer. Endless chains, formed of links having a hook for engaging the projections on the trays, may be substituted for the screws 1 - - 6. The complete charging and discharging device is mounted in a wheeled frame running on' rails to permit continuous baking or baking in batches.
