Abstract

In this study, copolymers of 1-butene with allyltrimethylsilane (TMAS) were synthesized via rac-ethylenebis(indenyl)zirconium chloride (rac-Et(Ind)2ZrCl2)/methylaluminoxane (MAO) catalyst. Combining 1H-NMR and Fourier transform infrared (FT-IR) spectroscopies, the microstructure of the copolymer was verified and the insertion rate of TMAS was calculated. Herein, we demonstrate that the isotacticity and thermal decomposition temperature of the copolymers decreased with the contents of allyltrimethylsilane in the copolymers. After blending the resultant copolymers with high isotactic poly(1-butene) powder (HI-PB), it was found that the 1-butene-allyltrimethylsilane copolymer (PB-TMAS) reduced the crystallization temperature, inhibited the formation of form I in the amorphous region at the initial stage of crystal transformation, and slowed down the crystalline transformation from form II to form I, but did not affect the time of the initial reduction of form II.

CrystEngComm is the forum for the design and understanding of crystalline materials. We welcome studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. We publish hypothesis-driven research into… how crystal design affects thermodynamics, phase transitional behaviours, polymorphism, morphology control, solid state reactivity (crystal-crystal solution-crystal, and gas-crystal reactions), optoelectronics, ferroelectric materials, non-linear optics, molecular and bulk magnetism, conductivity and quantum computing, catalysis, absorption and desorption, and mechanical properties. Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
