Problems solved by technology

However, the use of these hydrocarbon rubbers as impact modifiers for rigid PVC applications has been hampered by the fact that, when hydrocarbon rubbers are mixed into PVC compounds, they do not form compounds with effective impact modifiers. small rubbery microphase

Embodiment 1-1

[0026] A PVC composition was prepared in a Mitsui Mining Company Henschel mixer according to the following procedure: 100 parts of Shin-Etsu Chemical TK-1000 PVC was added to the mixer and the contents were heated until the temperature reached 113°F (45°C). Then add 0.5 parts STANN TM ONZ-100F tin stabilizer, and continue to blend. When a temperature of 140°F (60°C) was reached, 0.5 parts of Luwax(R) 0A2 powdered oxidized polyethylene wax, 0.5 parts of Luwax(R) A powdered polyethylene wax, 0.5 parts of SAK-CS-P(R) calcium stearate and 0.5 parts of Luvax(R) 2191 paraffin wax. Blending was continued until a temperature of 149°F (65°C) was reached, then 1.8 parts of Tyrin(R) 3600P chlorinated polyethylene was added, followed by 0.2 parts of Engage(R) 8842 ethylene-octene copolymer. Blending was continued again until a temperature of 185°F (85°C) was reached. Reduce the speed of the mixer to minimum and cool the mixer from the outside. When the temperature of the mixture reach...

Abstract

Polyvinyl chloride composition having excellent impact strength are disclosed, wherein this impact resistant composition comprises a vinyl chloride polymer and 2-8 parts of an impact modifier composition comprising at least one ethylene / alpha-olefin copolymer and at least one chlorinated olefin polymer per 100 parts of the vinyl chloride polymer, wherein the impact modifier composition comprises less than 1 part of the ethylene / alpha-olefin copolymer and the ratio of ethylene / alpha-olefin copolymer to the total modifier composition is less than 25%.

Description

technical field [0001] This invention relates to improved impact resistant vinyl chloride polymer compositions. More specifically, the present invention relates to polyvinyl chloride impact modifier compositions comprising a blend of hydrocarbon rubber and chlorinated polyethylene. Background technique [0002] Polyvinyl chloride (PVC), in both rigid and flexible forms, is widely used in various applications such as films, siding, sheets, pipes and pipes. Because rigid PVC is a hard, brittle thermoplastic polymer, it is often mixed with modifiers to form a composition that is less susceptible to failure when subjected to impact. Known polyvinyl chloride modifiers include polyacrylic resins, butadiene-containing polymers such as methacrylate butadiene styrene terpolymer (MBS), and chlorinated polyethylene (CPE) resins. For example, the use of a number of chlorinated and chlorosulfonated polyethylenes in blends with polyvinyl chloride is disclosed in US Patent Nos. 3,006,889...
