ütaTDilized vinyl halide hares dimensions

The invention relates to stabilizers for vinyl halide resins and resin compositions which stabilize them contain lizers and a vinyl halide resin.

There is a need for improved stabilizers for vinyl halide resins in order to counteract compositions are more resistant to elevated temperatures. Vinyl halide resin compositions with known stabilizers tend to decompose when heated. This decomposition shows up in the development of color and is particularly evident when waste resin is reprocessed in equipment operating at elevated temperatures will. Although the decomposition on heating affects the physical properties of the resins in material terms if not deteriorated, the discoloration limits its use on an industrial or commercial scale.

108Ö43 / 137 7 ^ 'naunspecteo

In addition to good heat resistance, it is necessary to that vinyl halide resins show little or no tendency to "plate-out" during their treatment. "Plateout" is the splitting off of one or more components of the vinyl halide composition, usually pigments and stabilizers, during the various stages in their treatment and deposition of these materials the metal surfaces of the manufacturing or treatment machine h. The deposits can and can cause streaks or stains on the finished products transfer the sheets or webs from roller ζμ roller or affect the removal of the product from the mold.

Rs is required that the vinyl halide resin compositions according to the invention contain only a small amount of stabilizer. It has been found that as little as 0.5 weight percent of the stabilizer based on the weight of the vinyl halide resin produces a remarkable improvement in the heat and light resistance and the resistance to plate-out of the composition. About 10% or more of stabilizer can be used,

Vinyl halide is usually and preferably the chloride, but the bromide and fluoride can also be used, but copolymers which are useful in the practice of the invention are those which are composed of at least 70 pounds of vinyl halide and up to 30 pounds of the mixed monomer are made. The invention is also applicable to mixtures of polyvinyl chloride in a predominant proportion with a minor proportion of such other synthetic resins, such as chlorinated polyethylene, polyacrylate and polymethacrylic esters, and copolymers of acrylonitrile, butadiene and styrene.

Any of the conventional plasticizers for vinyl halide resins can be used in the stabilized compositions according to the invention. These include e.g. B. Octyl phthalate, ibutyl sebacate, tricresyl phosphate or the like. The plasticizer is generally present in an amount of 5 to 100% by weight, based on the weight of the vinyl halide resin. Other heat and light stabilizers and pigments, Fillers, dyes, extenders, solvents or the like can be used in the production of the stabilized resin compositions.

109843/1377

The stabilized vinyl halide resin breeds can be prepared by any convenient method will. In general, it is preferred to combine the stabilizer with the vinyl halide resin, the plasticizer and other ingredients, if any, with or without a < volatile solvent to mix and the resulting mixture on rollers at a temperature of about Grind 93 to 177 ° C (200 to 350 ° F) until homogeneous is.

If necessary, the Stabilizer can be incorporated by dissolving in a solvent for the resin and then the stabilized Resin can be obtained.

C. Stabilized polyvinyl chloride resin compositions were prepared according to the following procedure: A mixture of, parts of polyvinyl chloride (Geon 101 EP), 67.5 parts of di-2-ethylhexyl phthalate and 7 * 5 parts of epoxidized in soybean oil was 4.5 parts of either stabilizer 2A or des Comparative stabilizer 2B added. The resulting mixture was mixed at fc-3-.i room temperature and then fed to a steam heated, variable speed, two roll mill, the surface temperature of which was maintained at approximately 166 ° C (330 ° P). The mixture was milled for five minutes and then removed from the rolls as a flexible, homogeneous web or as a flexible, homogeneous sheet with a thickness of about 0.114 cm (0.045 inch).

The heat stability of the compositions was determined by χ 2.54 2.54 cm (1 χ 1 inch) samples were cut from the coming out of the mill train, in a forced circulation air oven at about 177 ⁰ C (350 ° F) and the samples removed every 4 hours.

The inclination of the stabilizers towards "plate-out" was measured by producing a mass by the milling process described above which, in addition to the

Polyvinyl chloride resin, the plasticizer, the epoxidized soybean oil and the stabilizer contained a portion of Permanent Red '2B, a red pigment known for "plate-out". After milling at approximately 144 ° C (300 ° F) for 10 minutes, the mass was removed from the mixer. Then, without the mixer rollers being cleaned in between, a white "clean-up" composition was run through the mixer. This mixture was made from 100 parts of polyvinyl chloride, 30 parts of DjL-2-ethylhexyl phthalate, 10 parts of calcium carbonate, 1 part of titanium dioxide (rutile) and 0.5 part of calcium stearate. The tendency of this mass to “plate-out” was determined by the degree of coloration of the “cleaning” mass. A numerical scale was used to show the "plate-out" evaluation of the masses. On this scale, a rating of 1 means that no plate-out has taken place) 2 means a light pink color; 3 a pink color; 5 a light red color, 8 a red color; and 10 a dark red coloration of the "cleaning ¹¹ compound. For most technical applications, the compounds preferably have a" plate-out "rating of 1 to 3.
