Which of the following statements about polymers is/are correct?
1) Polypropylene and polyethylene are high molecular weight alkenes.
2) Addition polymers must be made from monomers which have at least one double or triple bond somewhere in the molecule.
3) Condensation polymerization reactions produce small molecules,like H₂O,as byproducts to the polymer formation.

Question

Quizplus · Accepted Answer

1) This statement is correct. Polypropylene and polyethylene are polymers made from alkenes that have been polymerized together to form long molecular chains. 2) This statement is also correct. Addition polymerization requires monomers with at least one double or triple bond, so that they can add to each other and form a larger polymer chain. 3) This statement is true. Condensation polymerization reactions produce small molecules such as water or methanol as byproducts of the reaction, which are eliminated in order to form the larger polymer molecule. The formula H₂O is an example of a byproduct in a polyamide condensation reaction.
