“…For example, three different helical structures can be produced by solution crystallization of isotactic poly-1-butene (Holland and Miller, 1964;Chau and Geil, 1984). The corresponding helices have 3 X -, 13 4 -, and 4 Xsymmetries with oaxis repeat distances of 0.65, 2.11 and 0.76 nm, and unit cells with hexagonal, tetragonal and orthorhombic symmetries respectively (Luciani et al, 1988). Note that, although significantly different in terms of helix and unit cell symmetries, all three helices correspond to conformations located near the minimum of the conformational energy maps of isotactic polyolefins shown in Fig.…”

“…Polybutene‐1 (PB‐1) homopolymer and copolymers are the typical polymorphic polymers, which have different crystalline modifications of Forms I/I′, II, and III. These different crystallite structures largely influence the practical applications in high‐pressure tanks, pumps, hot‐water pipes, and so on . The different PB‐1 modifications can be distinguished by the chain conformation and packing mode of segmental stems.…”

The stretching‐induced phase transition from tetragonal Form II to hexagonal Form I and the evolution of corresponding crystallite orientation were studied for the butene‐1/ethylene random copolymer with 1.5 mol % ethylene by using a combination of tensile test and in situ wide‐angle X‐ray diffraction. Three orientation pathways were distinguished for II‐I phase transition, including phase transition accomplishing within off‐axis oriented crystallites (Orientation Pathway 1), phase transition with simultaneous formation of highly oriented crystallites (Orientation Pathway 2), and phase transition occurring within the highly oriented crystallites already formed (Orientation Pathway 3). The kinetics of II‐I transition was correlated with the macroscopic mechanical response, which exhibits a strong dependence on orientation. In Orientation Pathway 1, the triggering of phase transition corresponds to the mechanical yielding. More interestingly, the kinetics of transition exhibits the identical dependence on stress. However, in Orientation Pathways 2 and 3, appearance of the highly oriented crystallites substantially alters transition kinetics, which is tentatively associated with the stress bearing by interstack tie chains. © 2018 Wiley Periodicals, Inc.

“…Isotactic poly(1‐butene) (iPB‐1), synthesized with butene‐1 monomer by Ziegler–Natta‐type catalyst,1 is one kind of semicrystalline thermoplastic polyolefin with many attractive properties, such as high creep resistance, low stiffness, good impact behavior, excellent elastic recovery, and high temperature resistance 2, 3. Despite these excellent properties, iPB‐1 is still limited in the field of application compared to those lighter polyolefins such as polyethylene (PE) and polypropylene (PP), mainly because of the higher cost of the raw material and the complicated transformation of crystal structure.…”

The β‐cyclodextrin (β‐CD) and γ‐cyclodextrin (γ‐CD) inclusion complexes (ICs) with four kinds of polyolefin were prepared. The crystallization behavior of isotactic poly(1‐butene) (iPB‐1) blended with these CDs and ICs was investigated by differential scanning calorimetry, polarized optical microscopy, and wide‐angle X‐ray diffraction. The iPB‐1 blended with the ICs was found to exhibit higher crystallization temperature (TC), smaller spherulites, and faster crystallization rate than neat iPB‐1. These results indicate that the ICs can act as nucleating agent on the crystallization of iPB‐1 and induce the accelerated crystallization. The guest molecules of ICs play an important role in the nucleation effect of ICs on the crystallization of iPB‐1. ICs with polyolefin having higher TC as guest molecules have higher nucleation effect than the one with polyolefin having lower TC as guest molecules. And, the CDs and ICs induce different crystal form of iPB‐1. The crystal of iPB‐1 blended with CDs is defective, whereas the crystal of iPB‐1 blended with ICs is more perfect. © 2010 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 48: 389–395, 2010
