Some characteristic properties of the α- and γ-forms of polyamide 6 are listed in Table 4.1 [173- 187]. The heats of fusion, ΔHf°, are the values reported by Illers [184]. It should be noted that other values for the α-form have been reported in the literature [180, 184, 186, 188-191] and Wunderlich has suggested a value of 230 J/g based on a compromise of various reports in the literature [192]. The effect of crystallization temperature and time on the formation of the α- versus γ-forms has been widely studied [185, 193, 194]. Gurato and his coworkers have shown that crystallization for extended periods of time below ~130 °C leads only to the γ-crystallites while above ~190 °C only the α-form is produced. Temperatures in between these limits result in a mixture of the two forms, with higher fractions of α-form being [produced at higher temperatures.]

Table 9.1 lists characteristic properties of the α- and γ-forms of nylon 6 [6-20]. The heats of fusion, ΔHf°, are the values reported by Illers [17]. It should be noted that other values for the α-form have been reported in the literature [13, 17, 19, 21-25] and Wunderlich has suggested a value of 230 J/g based on a compromise of various reports in the literature [26].

[...] The effect of crystallization temperature and time on the formation of the α versus γ-forms has been widely studied. For example, three independent investigations [18, 27, 28], have shown that crystallization for extend periods of

time below ~130°C leads solely to the γ-crystallites while above ~190°C only the α-form is produced. Temperatures in between these limits result in a mixture of the two forms, with higher fractions of α produced at higher temperatures. [...] [29]
