W.H. Carothers suggested classifying polymerization processes into which two types?

Explanation

W.H. Carothers classified polymerization processes into addition and condensation types. In addition polymerization, monomers add to each other without the loss of any small molecules, forming a polymer. In contrast, condensation polymerization involves the formation of a polymer through a condensation reaction where each step involves the loss of small molecules such as water or methanol.The other options do not refer to the types of polymerization processes:Linear and Branched refers to the structure of the polymer chains.Homopolymer and Copolymer describe the type of monomers used in the polymer, not the polymerization process itself.Thermoplastic and Thermosetting relate to the thermal properties and behavior of the polymers rather than their method of formation.
