The isotacticity is a measure of the stereoregularity of the polypropylene chain. In atactic polypropylene, the methyl group is randomly positioned on the chain backbone, whereas isotactic polypropylene possesses a methyl group at a regular position. Polypropylene is a relatively easy materials to injection mould in spite of its semicrystalline nature.
