Abstract
Vinyl ethers for use as bonding agents in solid rocket propellants are disclosed. The vinyl ether bonding agents are capable of polymerizing in the presence of and around the surface of ammonium perchlorate particles. The bonding agents of the present invention are added to the propellant in a range from about 0.1% to about 3% by weight concentration. Importantly, there is no increase in ammonia liberated above baseline propellant values and no increase in end of mix viscosities by using the vinyl ethers according to the present invention which provides substantial processing savings.
