These is shown in this paper the literature review and author's studies on the in vitro and in vivo ageing changes in plastic endotheses under certain conditions. The changes occurring in endotheses exposed to no major mechanical loads were considered in particular. Polyamides, polyethylene derivatives, polyesters, polyurethanes and silicone rubbers were found to belong to the polymers unstable under biological conditions.olyesters, polyurethanes and silicone rubbers were found to belong to the polymers unstable under biological conditions.
本文展示了关于在特定条件下塑料内膜体外和体内老化变化的文献综述及作者的研究。特别考虑了暴露于无主要机械负荷下的内膜所发生的变化。发现聚酰胺、聚乙烯衍生物、聚酯、聚氨酯和硅橡胶属于在生物条件下不稳定的聚合物。聚酯、聚氨酯和硅橡胶被发现属于在生物条件下不稳定的聚合物。
