Sunshine, Joel C. B. Sunshine, Sarah Bhutto, Imran T. Handa, James Green, Jordan J. Number-averaged molecular weight versus time of B5-S5-E7 in PBS at 37°C with agitation. <p>The half-life of the polymer in solution was 4.6 hr (R<sup>2</sup> = 0.984), and the polymer was almost completely degraded within 1 day.</p> molecular;b5-s5-e7;pbs 2013-02-20
