A more effective catalyst is tert-butyl alcohol (t-BS.) compared with benzyl alcohol (BzS). Polymerization of OLA in the presence of TSA at a noticeable rate occurs already at 130 watts. Adding an electron-donor molecules (water, DMSO, benzyl alcohol) to TSA results in lower molecular weight PLA. It is suggested that the presence of so-called "microwave effect" when OLA polymerization in the presence of alanine and TSA, i.e at the same temperature (215 ° C) and the time at different powers (280, 360 W) OLA polymerization proceeds at different rates.]]> Thu 19 Apr 2018 17:07:43 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000527039 Sat 06 May 2017 14:03:36 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000489142 Mon 19 Jun 2017 14:00:16 KRAT ]]>
