What is addition polymerization?

• Addition polymerization is a process that involves the removal of monomers to form a polymer

• Addition polymerization is a process that creates by-products during the formation of a polymer

• Addition polymerization is a process that only involves one type of monomer

• Addition polymerization is a process in which monomers are added together to form a polymer without the formation of any by-products.

What are monomers?

• Monomers are large molecules that can join together to form polymers.

• Monomers are inert substances that do not react with other molecules.

• Monomers are only found in inorganic compounds and not in organic compounds.

• Monomers are small molecules that can join together to form polymers.

What is the process of addition polymerization?

• The process of addition polymerization involves the removal of monomer units from a polymer chain.

• The process of addition polymerization involves the repeated addition of monomer units to form a polymer chain.

• The process of addition polymerization involves the combination of two different polymers to form a new polymer chain.

• The process of addition polymerization involves breaking down polymer chains into monomer units.

Give an example of addition polymerization.

• Polystyrene is an example of addition polymerization.

• Polyvinyl chloride is an example of addition polymerization.

• Polyethylene is an example of addition polymerization.

• Polypropylene is an example of addition polymerization.

What are the characteristics of addition polymerization?

• The characteristics of addition polymerization include the formation of short chains

• The involvement of saturated monomers

• The characteristics of addition polymerization include the formation of long chains, the involvement of unsaturated monomers, and the absence of any by-products.

• The presence of many by-products

What are the different types of monomers?

• Nucleic acids, enzymes, and fatty acids

• Fatty acids, lipids, and proteins

• Enzymes, carbohydrates, and lipids

• The different types of monomers include amino acids, nucleotides, and monosaccharides.

Explain the concept of chain growth polymerization.

• Chain growth polymerization is a process in which polymer chains grow by the addition of polymer units, initiated by a non-reactive center.

• Chain growth polymerization is a process in which polymer chains grow by the repeated addition of monomer units, initiated by a reactive center.

• Chain growth polymerization is a process in which polymer chains grow by the simultaneous addition and subtraction of monomer units.

• Chain growth polymerization is a process in which polymer chains grow by the repeated removal of monomer units.

What is the difference between addition and condensation polymerization?

• Addition polymerization involves the repeated addition of monomers without the formation of any byproducts, while condensation polymerization involves the formation of small molecules as byproducts during the polymerization process.

• Addition polymerization involves the formation of monomers, while condensation polymerization involves the formation of polymers

• Addition polymerization involves the formation of small molecules as byproducts, while condensation polymerization does not

• Addition polymerization involves the removal of small molecules as byproducts, while condensation polymerization does not

What are the advantages of addition polymerization?

• Generation of toxic by-products

• The advantages of addition polymerization include high reaction rates, the ability to produce a wide range of polymer structures, and the absence of by-products or waste products.

• Slow reaction rates

• Limited range of polymer structures

What are the disadvantages of addition polymerization?

• Addition polymerization does not require high temperatures and pressures

• Addition polymerization does not generate non-biodegradable polymers

• Addition polymerization does not have the potential for side reactions

• Some disadvantages of addition polymerization include the requirement for high temperatures and pressures, the potential for side reactions, and the generation of non-biodegradable polymers.
