There are three ldnds of unusually optical property spherulites in nylon1010: two-sectional (2)

asymmetric four-sectional (A4)

and six-sectional (6)spherulites' Rotating observation of the spherulites by a polarizing microscope (PLM)

the morphologies and colour distribution added the first red compensating plate arevariable periodly' The two -sectional

asymmetric four-sectional and six-sectionalspherulites have 3

1 and 2 kind changes: 2-A4-6(A)

2-A4(B)

2-2(C); A4-A4(D)

and 6-A4(E)

6-6(F) respectively.So that the all radii of these spherulites may are crystallographically inequivalent.
