<p>PURPOSE:To provide the titled container which has excellent transparency, is suitable for use as medical containers, can be easily molded and does not become sticky even when left to stand at a relatively high temp., by mixing a silicone oil with polypropylene in a specified weight ratio. CONSTITUTION:0.05-1pt.wt. silicone oil is mixed with 100pts.wt. propylene in a Henschel mixer. Silicone oils contg. a structural unit of the formula (wherein R, R' are each phenyl, methyl) are prefered. The mixture is molded into a container having the desired shape by injection, compression or blow molding, thus obtaining the desired container made of a polypropylene mixture. A container which is flexible, thin-walled and deep-drawn can be obtd. Mold release properties in preparing the container are improved.</p> |
