この発明は塩化ビニル系樹脂をペースとする高周波融着
性樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION 10. Background of the Invention [Technical Field] This invention relates to a high frequency weldable resin composition using a vinyl chloride resin as a paste.
塩化ビニル樹脂はこれを適当な可塑剤で可塑化してクロ
ーズド医療システムに用いられる柔軟な医療用バンクの
素材として用いられている。Vinyl chloride resin is plasticized with an appropriate plasticizer and used as a material for flexible medical banks used in closed medical systems.
可塑剤としてはソオクテルフタレー） （ＤＯＰ ）の
ような低分子可塑剤が多く使われていたが、これは薬液
や血液に溶出する可能性がちシ、低分子可塑剤に代るも
のが望まれている。As plasticizers, low-molecular plasticizers such as DOP (DOP) were often used, but these tended to be eluted into drug solutions and blood, so an alternative to low-molecular plasticizers was desired. It is rare.

であシ、ＤＯＰに代る可塑剤も前記の溶出の問題を回避
できるものであるとともに塩化ビニル樹脂の持っている
高周波融着性を損うものであっては々らない。By the way, when manufacturing medical bags, it is very convenient for manufacturing if the material has high frequency weldability, and a large amount of bags can be produced in a relatively short period of time. Vinyl chloride resin originally has such high-frequency fusion properties, and plasticizers that replace DOP can also avoid the above-mentioned elution problem and also have the high-frequency fusion properties of vinyl chloride resin. It is not uncommon for it to damage the

い。In other words, vinyl chloride resin containing an ethylene-vinyl acetate plasticizer has poor heat resistance and is not suitable for high-pressure steam sterilization. Vinyl chloride resin blended with a polyester plasticizer or a polyurethane plasticizer tends to allow water vapor to pass through, so the blood composition changes during blood storage, making it undesirable as a material for blood bags.

As a result of various studies, it was found that vinyl chloride resin can be plasticized by blending it with a styrene thermoplastic elastomer. However, this compound lacks high-frequency fusion properties, and upon further investigation, it was discovered that by further adding an olefin resin to this compound, a resin composition that achieves the desired purpose could be provided.

特に良好となる。Now, when a styrene-based thermoplastic elastomer is blended with the vinyl chloride-based resin, the flexibility necessary for a flexible medical pack material is imparted, but the high-frequency weldability, which greatly contributes to improved workability, shows a difference. . Therefore, in this invention, in order to improve this, an olefin resin is further blended. This olefin resin is 1.0 (g/

This is the case. From this point of view, the most preferable blending ratio of the resin composition of the present invention is 10 to 100 parts by weight of the styrene thermoplastic elastomer and 10 to 50 parts by weight of the olefin resin to 100 parts by weight of the vinyl chloride resin. be.
