The reaction of various dialdehydes and one diketone with pentaerythritol or pentaerythritol–dipentaerythritol mixtures, has produced a series of thermoplastic, Polyspiroacetal resins. These possess molecular weights up to 10,000, solubility in a limited range of solvents, and high melting points. Some of these, with an optimum amount of crosslinking, have produced transparent, tough, flexible films.
