摘要

在羰基的作用下，PE箔在小鼠肝脏匀浆中发生降解。用红外光谱法证实了酮(1715 cm−1)、酯(1745 cm−1)和醛(1730 cm−1)吸收带的生长。除含氧基团外，不饱和结构也很明显。确定的PE化学变化与植入塑料在人体组织中的类似发现进行了讨论。

Degradation of polyethylene exposed in mouse-liver homogenates by oxidation

A degradation of PE foils occurs in mouse-liver homogenates under an origination of carbonyl groups. The growth of ketonic (1715 cm⁻¹) above all and, then, of ester (1745 cm⁻¹) and aldehyde (1730 cm⁻¹) absorption bands has been proved by the method of infrared spectroscopy. Unsaturated structures are also evident besides oxygenous groups. The ascertained PE chemical changes are discussed with analogical findings of implanted plastics in a human organism.
