| 中文摘要 | poly(epsilon-caprolactone) (pcl), a saturated polyester, derived from ring-opening polymerization of epsilon-caprolactone, was chemically crosslinked with various amounts of benzoyl peroxide (bpo) by a two-step method by first evenly dispersing the bpo into the pcl matrix and then crosslinking at elevated temperature. the gel fraction increased with an increase in bpo content. the modified charlesby-pinner equation was used to calculate the ratio of chain scission and crosslinking. the results showed that both scission and crosslinking occurred, and that crosslinking predominated over scission. the number-average molecular weight between the crosslinks determined by the rubber elasticity theory using the hot set test showed a decrease with increasing bpo content. the melting temperature and crystallinity decreased with an increase in bpo content, and the crystallization temperature increased after crosslinking. dynamic mechanical analysis results showed a decrease in the glass transition temperature as a result of chemical crosslinking of pcl. this was explained by the observed reduction in crystallinity and the increase in free volume due to restrictions in chain packing. |
