Abstract: High impact polystyrene resins are provided having a surprisingly good combination of toughness and gloss characteristics. Such resins contain small (i.e., 0.1 to 0.4 micron) capsule morphology rubber particles in combination with relatively small (i.e., 0.25 to 1 micron) entanglement morphology rubber particles. It has been found that such resins are capable of providing Izod impact strength values in the range of 2.5 to 3.5 ft-lb/in (133.4 to 186.7 J/m) and higher at an overall volume average rubber size of less than 0.4 micron with corresponding gloss values in excess of 90 percent.

Abstract: Graft copolymerized maleimide-modified, impact resistant monovinylidene aromatic copolymer compositions have substantially improved impact strength and fatigue resistance properties when the swelling index thereof is 12 or greater and when the numerical difference in maleimide monomer content as between the grafted copolymer and matrix copolymer portions thereof differ by no more than 9 percentage points from each other. Such compositions are conveniently prepared by mass, solution or mass/suspension graft copolymerization processes and by deferring the addition of at least about 30 percent of the maleimide monomer ingredient to a point in the process after (and preferably only shortly after) phase inversion of the dissolved impact modifying rubbery polymer ingredient.

Abstract: Rubber modified styrene-acrylonitrile (ABS) resins are provided which have three different types of rubber particles. One particle type is a small, emulsion-produced particle and another is a large emulsion-produced particle. The third particle type is a large, mass-polymerized graft copolymer particle which comprisees as its rubbery substrate a diene polymer ingredient containing at least about 80 weight percent of a polymerized diene monomer and which constitutes no more than about 30 weight percent of the total rubber components contained within the compositions of interest. The resulting compositions have very high gloss characteristics and reduced gloss sensitivity to molding condition variations.

Abstract: A cold process fruit filling for pastry and bakery products is prepared ug two different starch components. The first starch component is a cold water swelling granular starch, while the second starch component is a pregelatinized starch. Such a combination of starches provided a means to produce a fruit filling without heating. The filling possesses heat stability to maintain the desired properties when the bakery product containing the filling is cooked.
