Introduction
1.Polymers are called macro molecules. 2.Polymers are made from small unit called monomers linked together by covalent bonds. 3.This process of formation of polymers from respective monomers is called polymerization. 4.Polymer properties are closely related to their molecular mass, size and structure. 5.The growth of the polymer chain during their synthesis is dependent upon the availability of the monomers in the reaction mixture. 6.The polymer sample contains chains of varying lengths and therefore its molecular mass is always expressed as an average. 7.The molecular mass of polymers can be determined by chemical and physical methods.
