Teflon
The polymers which are formed by the successive addition of monomer units without the elimination of smaller molecules and which result in the growth ofthe chain, are called chain growth polymers. In other words, addition polymers are chain growth polymers. eg, teflon (polytetrafluoro ethylene).
