State 4 differences between additional and condensation polymerisation?

The are severalÊ difference between addition and condensation polymerization.ÊThey include,Ê in addition polymerization monomers join up to form single substance without loss of any molecule unlike the later where there is loss of molecules,Ê reacting monomers have multipleÊ bondÊ in addition polymerization unlike the later whereÊ only functional groups of two monomers react, saturated monomers react in additional polymerization while the later involve unsaturated molecules and additional polymerization is a rapid process that produce high molecular weight polymers.
