I think the composition of the cylinders was a bit diferent from nitrate film base- it needed to be rigid rather than flexible for one thing. Also film base wasn't intended to be a very long lasting product. I've heard of some early celuloid records shrinking badly but most survive with little or no chemical deterioration. The main cause of breakage is if the core swells.
