ia evaporation procss. The crystalline morphology of these films was investigated by means of ploarized optical microscopy and scanning electron microscopy. Normal spherulites with a low growth rate formed in the casting films. The different morphologies of spherulite appeared in the filims cast from the solutins with diiferent concentration. After further crystallizing for a few days, the spherulites were decorated by thousands of needlelike extended-chain crystals, which had a typical size of ～50μm(length)×2～5μm(lenght)×1～2μm(width)×1～2μm(height) in the fringe part of the spherulite. The real concentration for crystallization was dedtermined solution.
