| Abstract: | Correlations have been investigated between the content of short isotactic segments and thermal properties in some propylene/olefin random copolymers. Polypropylene copolymers modified by ethylene show variations different from those for copolymers modified by ethylene and butene. However, in both cases, the weldability temperature decreases on increasing the comonomer concentration. |
