Abstract

PURPOSE:To prepare the title compsn. excellent in antistatic properties without detriment to transparency. thermal stability, processability, etc., by compounding a vinyl chloride resin with a polyhydric alcohol hydroxystearate. CONSTITUTION:The title compsn. is pred. by compounding a vinyl chloride homopolymer or a copolymer contg. at least 50% vinyl chloride units with a polyhydric alcohol hydroxystearate as an antistatic agent. The hydroxystearate is prepd. by the esterification of hydroxystearic acid with a polyhydric alcohol such as glycerin, sorbitan, or trimethylolpropane. Another antistatic agent (e.g. glycerin monostearate) may be compounded together with the hydroxystearate.

[Prior art] Hard vinyl chloride resin has good transparency;
Although it is used in a wide range of fields due to its excellent strength, it is easily charged with static electricity. Antistatic agents are used to prevent static electricity on hard vinyl chloride resins, but when it comes to kneaded antistatic agents, those that have an antistatic effect tend to have lower transparency and thermal stability. Those with good properties and stability did not have an antistatic effect. For this reason, surface-applied antistatic agents have been used, but there are problems with sustainability of the effect, workability of resin processing, etc., and therefore there is a demand for a kneaded-in antistatic agent.
