Abstract: A gasketing compound with low plasticizer migration comprises a polyvinyl chloride resin with an inherent viscosity at or above about 0.92 and a porosity at or above 24 cubic centimeters per gram, and a polymeric plasticizer. The gasketing compound is extruded to form a gasket which produces little or no marring of the paint surface with which the gasket is in contact.

Abstract: A sill cover article for automobiles and other vehicles which has a first, relatively rigid sill cover portion and a second, relatively flexible lower door sealing portion that is manufactured as a single component and can be attached to a vehicle in a single mounting operation. The sill cover article is preferably manufactured of two materials of different durometer which are coextruded to form a single component. The sill cover article or a portion thereof may be provided with various coatings and/or additives to provide the article with desired properties. For example, the lower door sealing portion may be provided with an ice-release agent to prevent ice from forming on a surface thereof. The sill cover article of the present invention provides a reduction in assembly time, inventory requirements and overall manufacturing costs of a vehicle.

Abstract: An emulsion acrylate copolymer is provided which unexpectedly is an effective magnetic binder inasmuch as it can be loaded with high amounts of one or more magnetic particles such as ferrite or ferrite containing materials to provide a flexible permanent type magnetic composition of high magnetic energy. The copolymer is made from an alkyl acrylate and a salt of 2-acrylamido-2-methylpropane sulfonic acid (AMPS). A carboxylated ethoxy alkyl phenol surfactant is utilized which provides good processability and permits a blend of the magnetic particles with the emulsion acrylate copolymer to be precipitated from a latex solution by high shear mixing. Flexible high magnetic energy magnets can thus be made and utilized in various applications such as refrigerator doors, electrical motors, and the like.

Abstract: An animal tag assembly is disclosed having at least one relatively wide section along the length of the body of said tag, thicker than the body of said tag and containing a connector and optionally a washer to enable the tag to rotate. The body of the tag including edge beads is extruded from a powdered or finely divided compounded plasticized vinylchloride polymer insecticide releasing composition at temperatures below about 150.degree. C., preferably below about 125.degree. C., to provide a tag after extrusion with retention of at least about 90+% by weight of the migratory and volatile insecticide which is initially contained. The connector and washer, free of insecticide, are suitably compounded and molded from tough, impact resistant and relatively hard thermoplastics such as one of the acrylonitrile-butadiene-styrene copolymers, polystryenes, polyvinyl acetals, rigid polyvinyl chlorides, nylons and poly alpha olefins.
