Polymer Chemistry Concepts

What type of polymerization is initiated by an anion, often using monomers with electron-withdrawing groups?

What is the name of a polymer chain that lacks a regular arrangement of substituents along its backbone?

What type of compound contains the -N=N-. functional group and is often used as thermal initiators in radical polymerization?

What is the name of the process where an active radical is transferred to another molecule, ending the growth of a chain and potentially initiating a new one?

What is the name of the temperature above which the rate of depolymerization exceeds the rate of polymerization?

What kind of polymerization involves the rapid addition of monomers to an active center?

What term refers to the spatial arrangement of atoms in a polymer chain that can be changed by rotation around single bonds?

What type of polymerization involves the use of two or more different monomers?

What is the name for the degree of structural order in a solid polymer, where chains arrange in a regular, repeating lattice?

What term refers to the number of monomer units in a polymer chain?

What is the name of a technique for measuring the volume change of a material as a function of temperature, often used to determine the glass transition temperature?

What term refers to a measure of the breadth of the molecular weight distribution, calculated as the ratio of weight-average molecular weight to number-average molecular weight?
