Claim 3
Dependent Claim
145 words
A solid propellant composition comprising from about 5 to about 55 parts by weight of a cross-linked polyurethane resin binder which comprises the reaction product of the compound having at least two active hydrogen groups as determined by the Zerewitinoff method and capable of polymerizing with an isocyanate, and an organic compound having as its sole reactive groups at least two isocyanate groups; and from about 95 parts to about 45 parts by weight of an oxidizer composition comprising a compound having the general formula (R)m (NH4 m X)n wherein R is an organic radical having a valence equal to n; X is selected from the group consisting of perchlorate and nitrate; n is an integer of from 1 to 2; and m is an integer of frOm 1 to 3 when n equal 1, and m is equal to 1 when n equals 2.
