i) Which of the following is not true about step-growth polymers? Formation of step-growth polymers usually results in the loss of a small molecule. Step-growth polymers are formed by the reaction of bifunctional molecules. Step-growth polymers can be formed by a free radical mechanism. Step-growth polymers are also known as condensation polymers. Step-growth polymers do not reach high molecular weight until the reaction has gone nearly to completion. ii) Which of the following are not termination methods in radical polymerization?...
