An important concept in understanding the link between the structure of polypropylene and its properties is tacticity. The relative orientation of each methyl group relative to the methyl groups on neighboring monomers has a strong effect on the finished polymer's ability to form crystals, because each methyl group takes up space and constrains backbone bending.
