Chemical Structure of Isotactic Polypropylene Isotactic Polypropylene has a simple molecular structure. It contains a carbon ‘backbone’ chain whereby carbon is bonded to carbon atoms in a polymer chain, carbon is bonded to hydrogen atoms and methyl groups. (CH3). All the methyl groups are positioned on the same side of the chain, resulting in a regular and uniform structure of polymer. Polypropylene forms the head to tail structure through polymerization. There is strong covalent bonds between these atoms but weak Van der waals force (dipole-dipole force) between Polypropylene molecules. Isotactic Polypropylene forms a somewhat tetrahedral arrangement and its molecules are asymmetrical. These molecules form a long polymer chain.…show more content…

It can be moulded into different shapes and sizes and hence, can be put to many uses (material used to make chairs, containers, tools etc.) It is hard but flexible. (semi-rigid) It is lightweight! Polypropylene has a chemical formula of (C3H6)n. It is completely, 100% RECYCLABLE! Polypropylene has a code of 5 amongst the other types of plastics. It is one of the safer plastics! They are microwavable! Polypropylene is also dishwasher safe! It has softening region of about 150 °C and a melting point of 160-170 °C. It is resistant to most acids and alkalines as well as organic solvents It has a good chemical and heat resistance compared to other plastics. It is a non-conductor of
