摘要： Disclosed herein are core-shell polymers having an alkali-insoluble, emulsion polymer core and an alkali-soluble, emulsion polymer shell attached or associated with said core so that upon dissolving said shell with alkali, a portion of said shell remains attached or associated with said core. Also disclosed are compositions wherein said shell polymer has been neutralized and substantially, but not totally, dissolved so as to form a blend of neutralized core-shell polymer and an aqueous solution of neutralized shell polymer.

摘要： 1. Compositions suitable for the manufacture of propellants consisting essentially ofA. 15 to 40 parts of a monomer selected from the group consisting of compounds of the formula ##STR1## in which R is selected from the group consisting of hydrogen, methyl and ethyl, and R.sup.1 is selected from the group consisting of ##STR2## in which n is an integer from 1 to 5, and R.sup.4 is selected from the group consisting of H and CH.sub.3, ##STR3## in which R.sup.2 is selected from the group consisting of hydrogen and lower alkyl containing 1 to 4 carbon atoms, and R.sup.3 is selected from the group consisting of hydrogen and lower alkyl containing 1 to 4 carbon atoms,B. greater than 0 and less than 20 parts of a plasticizer for the polymers prepared by polymerizing the monomers of A), said plasticizers consisting essentially of a major proportion of compounds containing groups selected from the group consisting of NF.sub.2 and ONO.sub.2,C. 40 to 60 parts of a solid powdered oxidizer, selected from the group consisting of lithium, sodium, potassium and ammonium salts of nitric and perchloric acids andD. 0 to 25 parts of a finely particled readily combustible solid selected from the group consisting of carbon black, aluminum, magnesium, zinc, zirconium, boron, and beryllium.
