Figure 3 . Film formation from aqueous dispersion and crystallization Bottom: Time dependence of the shear modulus G' of an amorphous (O) and a semicrystalline () polychloroprene at 25 °C. The frequency was 5.32 MHz, and the final film thickness was about 120 mm. Top: Polarization micrograph of the semicrystalline polychloroprene sample after 2 h of isothermal crystallization.
