It's unlikely to be the plastic itself: LEGO typically uses acrylonitrile butadiene styrene, or ABS, plastic—a highly durable polymer that keeps the pieces strong for building, or what LEGO calls " clutch power."

这不太可能是身的问题：乐高通常使用丙烯腈-丁二烯-苯乙烯（ABS），这是一种高度耐用的聚合物，能够保持积木的强度，并提供乐高所谓的“合力”。

Precursor is probably acrylic nitrill or pan which is produced by the petrochemicals industry Pitch obtained from car is sometimes used instead.

前驱体可能是丙烯腈或聚丙烯腈，这些是由石化工业产的。有时会使用从煤焦油中获得的沥青作为替代。

All of these materials come from natural resins except for carbon fiber, a synthetic resin commonly made from polyacrylonitrile.

所有这些材都来自天然树脂，碳纤维除外，碳纤维是一种通常由聚丙烯腈制成的合成树脂。

The fibers consist of carbonized polymers made up of long strings of molecules bound together by the powerful bonds between carbon atoms. The fibers are made by heating a pre-c in a protective atmosphere of inert gases, The most commonly used.

这些纤维由碳化的聚合物组成， 聚合物是由长链分子通过碳原子之间的强键连接在一起形成的。 这些纤维是通过在惰性气体保护气氛中加热前驱体制成的，最常用的前驱体是聚丙烯腈。
