Molecular weights, molecular weight distribution, and the determined hydroxyl end groups of different pre-polymer variations determined via GPC.

Variation (PDET Pre-Polymer)	Mw	Mn	Mw/Mn	OH (mmol/g) *
Very high molecular weight	6542	6104	1.072	--
High molecular weight	5190	3657	1.419	1.1
Low molecular weight	3538	1031	3.4	1.6
Very low molecular weight **	1366	1090	1.25	2.7

* Determined by end group analysis; ** Data were reported previously by our group [25].
