Abstract
A support material for use in an additive manufacturing system, which includes a thermoplastic copolymer polymerized from monomers comprising acid-functional monomers having carboxylic acid groups, and one or more non-acid-functional monomers, where a portion of the carboxylic acid groups are neutralized with a base having an alkali metal cation. The thermoplastic copolymer has a high glass transition temperature and melt processing temperature, and is thermally stable at its melt processing temperature. The neutralized thermoplastic copolymer is soluble in an alkaline aqueous solution.
