The crystalline ability of polymers are affected essentially by the polymer structure.The factor includes symmetry,three-dimensional tacticity of molecular chain etc.The more flexible polymer chain becomes,the worse crystalline ability of polymer will be.The introduction of rigid unit can can improve the above symmetry and spacial tacticity of polymer chains.
