Abstract
This invention relates to novel polymers containing high energy groups comprising a polyether having the general formula ##STR1## WHEREIN EACH R is an alkyl or hydrogen and n is an integer from about 10 to 60. The preparation of these novel polyethers and their use as binder materials for high energy solid propellants is also described.
Claims13
A polymer containing high energy groups and improved thermal stability which comprises a polyester having repeating units of ##STR15## wherein each R is a lower alkyl radial or hydrogen and n is an integer between 10 and 60.
A process for preparing high energy polymeric materials having improved thermal stability which comprises reacting a polyether having the general formula ##STR16## wherein each R is an alkyl radical or hydrogen and n is an integer between 10 and 60 with an organic base having a K.sub.b of less than 1 .times. 10.sup.-3.
