The beta irradiation, as one of several possibilities how to modify the polymer properties resulted in isotactic polybutene-1 (PB-1) and its random copolymers with ethylene (E) mainly in chain scission without chain cross-linking. The original phase I did not change by irradiation, only the transformation rate of phase II to I increased with the irradiation dose and ethylene groups in PB-1/E copolymers. Beta irradiation decreased the sample crystallinity, crystal size, and perfection.
