    摘要: A process that is provided for agglomerating rubber particles of a rubbery latex. The process involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is affixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadiene-styrene graft copolymers.

    摘要: A process is provided for agglomerating small rubber particles in an aqueous latex to form large rubber particles. The process involves the addition of a water soluble organic acid and a water soluble organic anhydride to the latex prior to agglomeration of the rubber particles to facilitate agglomeration of the rubber particles into large rubber particles which are essentially free of coagulum. The latex of large rubber particles is useful in the preparation of ABS polyblends.

    摘要: Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.
