The solubility of oxidation‐cured polycarbosilane (PCS) fiber into benzene, tetrahydrofuran (THF), acetone, and ethanol was investigated. The solubility of the fiber in benzene and THF decreases as the curing temperature increases. The fiber cured at 433–463 K, however, shows higher solubility in acetone and ethanol than the original fiber and the fiber cured at 473 K. The remaining gels in benzene and THF keep their fibrous shape, while in acetone and ethanol often appear as swollen gels. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 65:261–265, 1997
