A plurality of solid polymer particles including an aromatic epoxy crosslinked with a hardener having at least two amino groups and at least one of an aromatic ring or a cycloaliphatic ring is disclosed. The solid polymer particles are useful, for example, as proppants. Mixtures of the plurality of particles and other particles, fluids containing the plurality of particles, methods of making the plurality of particles, and methods of fracturing a subterranean geological formation are also disclosed.
