Isodisperse Telechelic Polymers and their Polyurethane Derivatives.

Abstract

In this part of the Contract three other HTPBD samples have been prepared, characterised by the following molecular weights: No.4. Nominal M(sub n) = 1000; Experimental: M(sub n) = 1245; Polydispersity: M(sub w)/M(sub n) = 1,34; No.5. Nominal M(sub n)=1500; Experimental: M(sub n) = 1552; Polydispersity: M(sub w)/M(sub n) = 1,34; No.6. Nominal M(sub n) = 10000; Experimental: M(sub n) = 10800; Polydispersity: M(sub w)/M(sub n)= 1,95. The details of the polymerization recipe of the individual samples were given in our previous 2nd Interim Report (December 21, 1995. Contract No. N68171-95-C-9086). The samples were sent by air mail on January 25, 1996. The structures of the samples were characterised by FT-IR, (1)H-NMR and GPC investigations. The measurements are given graphically, their evaluations are summarised in the Table 1. The FT-IR spectra of the samples were recorded by a Bomem MB-100 spectrophotometer. jg p1
