Peel films of blends of low density polyethylene (LDPE) and random isotactic copolymers of butene‐1 with either ethylene (iPB‐Eth) or propylene (iPB‐Prop) were investigated regarding the effect of the copolymer composition on both the Form II mesophase to Form I crystal transformation of the copolymers, and the time‐dependent peel behavior of their blends with LDPE in peel films. In general, there is observed a decrease of the peel force with increasing concentration of both ethylene and propylene co‐units in random iPB‐1 based copolymers and their blends with LDPE, after completion of the Form II to Form I transformation. Thus, to tailor the peel force, either the content of the peel component in the blends, or the concentration of ethylene or propylene co‐units in the peel component may be varied. The effect of ethylene co‐units in the random copolymers on the peel force is distinctly larger than that of propylene co‐units. Parallel to the Form II to Form I transition of butene‐1 based copolymers, the peel force decreases with a rate which depends on the copolymer composition. The Form II to Form I transition in iPB‐Prop copolymers proceeds distinctly faster than in iPB‐Eth copolymers of identical concentration of co‐units. POLYM. ENG.
