A process for producing peroxydicarbonates comprising first reacting at least one inorganic peroxide with at least one alkali metal hydroxide to form at least one alkali metal peroxide. The at least one alkali metal peroxide is added to a mixture of at least one haloformate, at least one dispersant and water. The mixture is homogenized during the entire reaction to form a peroxydicarbonate. The peroxydicarbonate is dispersed as small droplets of from 1 to 10 microns in size in the aqueous mixture. The entire mixture is added to a polymerization reactor containing an ethylenically unsaturated monomer. The peroxydicarbonate functions as the free radical initiator to polymerize the monomer. The peroxydicarbonate is substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.

Method for producing peroxydicarbonates and their use in the radical polymerization of monomers

A process for producing organic peroxide initiators useful in the polymerization of ethylenically unsaturated monomers. The process for making the organic peroxides includes forming an aqueous emulsion of the organic peroxide. The organic peroxide is dispersed as small droplets of from 1 to 10 microns in size in the aqueous emulsion. The organic peroxide may be added to a polymerization reactor containing an ethylenically unsaturated monomer. The organic peroxide functions as a free radical initiator to polymerize the monomer. The organic peroxide may be substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.

The present invention to a method of synthesizing poly(vinyl halide) by means of a free radical polymerization which mimics a 'living' radical polymerization in the presence of an iodine containing chain transfer agent containing at least one iodine atom bonded to a primary carbon atom and having the formula:

Process for polymerizing vinyl chloride polymers with iodinated chain

The present invention relates to a method of synthesizing 1-chloro-1-iodoethane by reacting hydrogen iodide with vinyl chloride monomer in the presence of an iodine containing catalyst under certain specified conditions. The resulting product of the reaction is a high yield, high purity 1-chloro-1-iodoethane which is useful as a chain transfer agent in the polymerization of vinyl chloride monomer. The 1-chloro-1-iodoethane formed by the instant invention can be made separately in a conventional synthesis apparatus or the compound can be synthesized in situ in the reaction vessel used for polymerization of vinyl chloride. The in situ process comprises reacting substantially anhydrous hydrogen iodide with an excess of vinyl chloride monomer in the reactor in the presence of an iodine containing catalyst, preferably removing any catalyst and iodine, optionally charging additional vinyl chloride monomer with other polymerization auxiliaries, and initiating the polymerization thereof to form polyvinyl chloride by conventional methods.

Method for preparing 1-chloro-1-iodoethane

Rigid thermoplastic articles are disclosed which have reduced surface gloss. The reduced gloss is achieved by the use of a mixture of polymers having different viscoelastic properties. The preferred embodiment is a mixture of PVC and crosslinked PVC.

The present invention relates to a method of synthesizing 1-chloro-1-iodoethane by reacting hydrogen iodide with vinyl chloride monomer in the presence of an iodine containing catalyst under certain specified conditions. The resulting product of the reaction is a high yield, high purity 1-chloro-1-iodoethane. This 1-chloro-1-iodoethane is useful as a chain transfer agent in the polymerization of vinyl chloride monomer in a process which mimics a pseudo-living radical polymerization.

Optically transparent frosted polymeric articles are disclosed which can be produced in smooth molds. Polymeric articles, such as PVC bottles, are molded from a composition having two polymers with different viscoelastic properties. A particularly desirable composition is one containing both PVC and crosslinked PVC.
