Refractive index and composition of poly(methyl methacrylate) fracture surface layers

By using the phenomenon of total internal reflection of light the refractive index of the thin layer present on fresh poly(methyl methacrylate) fracture surfaces has been measured. The fracture surface refractive index, 1.32, is the same as that of the craze in the same polymer. The fracture surface...

Description
Summary:By using the phenomenon of total internal reflection of light the refractive index of the thin layer present on fresh poly(methyl methacrylate) fracture surfaces has been measured. The fracture surface refractive index, 1.32, is the same as that of the craze in the same polymer. The fracture surface layer is accordingly thought to be craze like in structure.
