Polymers addition
WebThe main difference between addition and condensation polymers is the reaction used to form them. Condensation polymers are formed in condensation reactions between molecules with different functional groups. Addition polymers are formed in addition reactions between molecules with a double bond. WebHomopolymers – The formation of addition polymers due to the polymerization of single polymeric species is called a homopolymer. For example, polythene (C 2 H 4) n). …
