Compounds and compositions comprising specific metal salts of bicyclo[2.2.1 ]heptane dicarboxylate salts in order to provide highly desirable properties within polyolefin articles are provided. The inventive salts and derivatives thereof are useful as nucleating and/or clarifying agents for such polyolefin, provide excellent crystallization temperatures, stiffness, and calcium stearate compatibility within target polyolefin. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Polyolefin additive compositions and methods of producing polyolefin with such compounds are also contemplated within this invention.

Low molecular weight copolymers of (1) acrylic acid esters or methacrylic acid esters of alcohols such as methanol with (2) esters of bicyclic alcohols such as isobornyl alcohol and unsaturated acids such as methacrylic acid, as contrasted with high molecular weight copolymers of such monomers (1) and (2) (see U.S. patent No. 3,485,775) and as contrasted to other acrylic polymers, are found to be exceptional in compatibility with practically all types of hard coating resins, and to lower the flow temperature of the mixture when using powder coating methods such as an electrostatic spray or a fluidized bed, electrostatic or not, as compared with the use of the hard coating resin alone.

Powder coatings containing copolymer containing isobornyl methacrylate as melt flow modifier

This invention concerns fibers of amorphous polyesters of terephthalic acid or an ester forming derivative thereof and from about 60 mole percent to 100 mole percent 1,2-propylene glycol and from 0 to about 40 mole percent ethylene glycol. These fibers are useful for the production of bonded coherent cigarette filters, nonwoven fabrics and the like.

Plastic compositions based on poly(alkylene terephthalates), in particular poly(1,2-propylene terephthalate) polyesters intermixed in polyvinyl chloride compositions, are provided. The compositions of this invention provide improved processing characteristics with reduced melt viscosity and improved physical and mechanical properties such as tensile properties and weathering resistance.

Terephthalic acid/1,2-propylene glycol polyester modifiers for polyvinyl chloride compositions

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
