This invention relates to the use of ethylene/propylene random copolymers for the production of films having low-haze. In particular, the present invention involves the use of ethylene/propylene random copolymer comprising 90-96.5 wt % propylene and 3.5-10 wt % ethylene demonstrated to have low haze. This invention also relates to an ethylene/propylene random copolymer composition comprising about 3.5-10 wt % ethylene content and about 90-96.5 wt % propylene content, for production of a low-haze film.

A process for preparing polymeric particles involves a stepwise or gradient emulsion polymerization. The polymeric particles contain polymerized units of methacrylic acid and further monomers, with an overall monomer composition by weight of polymerized units of 5 to 25% by weight of methacrylic acid and 75 to 95% by weight of further monomers. The further monomers are selected from C.sub.1- to C.sub.4-alkylesters of methacrylic acid and/or C.sub.1- to C.sub.4-alkylesters of acrylic acid. The ratio by weight of polymerized units of methacrylic acid to further monomers increases stepwise or in a gradient from the center to the surface of the particles and the polymeric particles are obtained in the form of an aqueous dispersion.

The present specification relates to a battery, comprising an anode, a cathode, an electrolyte disposed between the anode and the cathode, a halogen in contact with the cathode, and a metal in contact with the anode, wherein the halogen is in contact with a polymeric halogen sequestering agent (HSA) which is a polymer comprising a moiety capable of sequestering the halogen.

Provided is an aqueous dispersion composition that comprises a carboxyl-group-containing water-soluble copolymer in a relatively high concentration, but has intact handleability.
