【発明の詳細な説明】 〔産業上の利用分野〕 本発明は耐食品汚染性に優れ、かつ、顔料を使用せずに
白色に着色したポリ4-メチル‐1-ペンテンを提供するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides poly4-methyl-1-pentene which is excellent in food stain resistance and which is colored white without using a pigment. .
学校の給食や食堂で使用される食器には、軽量で破損し
難く丈夫であるといつた取扱い性の面からポリプロピレ
ン製の食器が使用されている。For tableware used in school lunches and cafeterias, polypropylene tableware is used because it is lightweight, durable, and easy to handle.
ところで、食器の他の要求性能として食器に付着した食
品を簡単に洗い流すことができ食器を着色することがな
いかとい問題すなわち耐食品汚染性がある。すなわち、

た。ところが従来のポリプロピレン製食器では、耐食品
汚染性の面で不十分なところがあり、耐熱性不足によつ
て電子レンジにかけられないという問題点がある。By the way, as another required performance of tableware, there is a problem that foodstuffs adhering to the tableware can be easily washed off and the tableware is colored, that is, food stain resistance. That is,
If you can easily clean the dishes with curry, ketchup, sauce, and other food items for a long time by washing, it will be economically advantageous because the washing work can be shortened in schools and cafeterias that handle a large amount of dishes. Also, due to the widespread use of microwave ovens in recent years,
Tableware performance that can be used in a microwave oven has also been required. However, conventional polypropylene tableware is insufficient in terms of food stain resistance, and has a problem that it cannot be used in a microwave oven due to insufficient heat resistance.

て調理することも可能である。The lack of heat resistance can be solved by using polycarbonate or polysulfone, but it is insufficient in terms of food stain resistance. On the other hand, poly-4-methyl-1-pentene has excellent heat resistance and excellent electric characteristics, and thus can be used in a microwave oven and has excellent food stain resistance. Therefore, the tableware formed from poly-4-methyl-1-pentene has good food stain resistance and can be cooked in a microwave oven.

判つた。By the way, tableware is often colored white in order to make the dishes look beautiful, especially on the side where the dishes are placed. Since poly 4-methyl-1-pentene is known to be transparent,
The present inventors also examined whitening of tableware using poly-4-methyl-1-pentene. Usually, various pigments are used for whitening resins, but when poly 4-methyl-1-pentene is mixed with a filler such as pigment, it is one of the characteristics of poly 4-methyl-1-pentene. It has been found that it deteriorates the food stain resistance.
