使用丁基锂作为引发剂，通过阴离子聚合制备了重均分子量为 33 × 103g mol-1 的聚戊内酯 (PVL) 样品。该样品的玻璃化转变温度为 206K，熔点为 332K。这两个值都非常接近聚己内酯 (PCL) 的值。 PVL 以及 PCL 均可与聚氯乙烯混溶。还报告了 PVL 的 X 射线数据、应力-应变曲线和动态机械测量。
A poly(valerolactone) (PVL) sample, having a weight average molecular weight of 33 × 103g mol−1, has been prepared by an anionic polymerization using butyl lithium as initiator. This sample has a glass transition temperature of 206K and a melting point of 332K. Both of these values are very close to those found for poly(caprolactone) (PCL). PVL, as well as PCL, is miscible with poly(vinyl chloride). X-ray data, stress-strain curves, and dynamic mechanical measurements of PVL are also reported.
