1. Examples of Step-growth Polymers by Various Reactions: In this section, the lecture likely discussed different chemical reactions that lead to step-growth polymerization. These reactions could include condensation reactions, such as esterification and amidation, and other types of reactions like Michael addition.
2. Theoretical Treatment of Linear Step Polymerization: This part of the lecture might have focused on the mathematical and theoretical aspects of linear step polymerization. It would involve discussing the kinetic equations, rate constants, and how the reaction progresses to form larger polymer chains.
3. Functionality of Monomers: This topic probably covered the concept of functionality in monomers. Functionality refers to the number of reactive sites in a monomer molecule that can participate in polymerization reactions. Higher functionality leads to branching in polymers.
4. Linear Step Polymerization: DP vs. Conversion: This section may have explained the relationship between the degree of polymerization (DP) and conversion in linear step polymerization. As the reaction proceeds, monomers join together, increasing the DP while decreasing the conversion.
5. Molecular Weight Control in Linear Polymerization: Here, the lecture likely discussed strategies to control the molecular weight of polymers during linear polymerization. Techniques like using different ratios of monomers or controlling reaction conditions can influence the final polymer's molecular weight.
