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?...

Critical Thinking Questions: 2) The polymerization of ethylene ("monomer") with a radical initiator follows the same chain reaction. Please write the mechanism (all arrows) from ethylene (==ethene) to polyethylene). Start with an initiator of R-R. After breaking the initiator bond to your radicals, use either radical for your 1"' reaction with ethylene. Indicate repeating reactions by multiple arrows. Write the final product in a common short...
