    摘要： Pencils having a core within a barrel, the barrel being formed from a blend of at least two transparent polymers which are incompatible and form separate phases within the blend, the polymers having refractive indices which differ by not more than 0.02 when measured under substantially the same conditions. Blends for use in producing the barrels of such pencils have shown good sharpenability combined with high transparency. The latter enables the core of the pencils to be clearly visible through their barrels.

    摘要翻译： 铅笔在桶内具有芯，桶由至少两种不相容的透明聚合物的共混物形成，并且在共混物内形成分开的相，聚合物的折射指数在基本相同的条件下测量时，其折射率不大于0.02 条件。 用于生产这种铅笔的桶的混合物显示出良好的可锐化性以及高透明度。 后者使得铅笔的核心通过它们的桶清晰可见。
