Which of the following would be expected as the result of polymerization reactions in which four monomers are linked to form a straight chain polymer? Energy is released and four water molecules are produced. Energy is consumed and four water molecules are consumed. Energy is released and three water molecules are produced. Energy is consumed and three water molecules are produced. Energy is released and three water molecules are consumed.

Are the IMFs stronger in relaxed or stretched rubber?

Please elaborate about Polymerization

Draw the structure of the polymer formed when the following monomer reacts with sodium methoxide. You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Use R1 groups to indicate the points where the polymer repeats. The R group tool is located in the charges and lone pairs drop-down menu. P aste ..

The following table lists molecular weight data for a polypropylene material. compute the following.  a) the numbr-average molecular weight  2) the weight-average molecular weight  3) the degree of polymerization

Addition (chain-growth) polymerization reactions often terminate by combination or disproportionation. However, there is another class of deactivation reactions, called chain transfer reactions, which are usually relevant to the final degree of polymerization (dp). How might you expect the dp of a polymerization reaction deactivated by chain transfer compare/contrast with polymerizations terminated by combination or disproportionation?
