Answer to Question 1

Crosslinking is the process of connecting polymer chains with covalent bonds. When this occurs, the total length of the polymer chains

Answer to Question 2

Addition polymerization will give branched polymers. This branching results from the loss of an atom, usually hydrogen, during the polymerization process which causes a free radical to form at the site where the hydrogen atom was previously located. This free radical is then able to bond with other free radicals, as on the end of a growing polymer chain, or with a monomer and begin a chain which grows as a branch off the main backbone. Condensation is less likely to branch because there is no mechanism that will create a reactive site in the middle of a chain.
