Bulk Polymerization: The polymerization occurs in a single homogeneous phase.
Solution Polymerization: The polymerization occurs in a solvent to create a polymer solution.
Suspension Polymerization: Polymerization occurs in a liquid medium, but the monomer droplets are suspended in the liquid medium.
"There are many forms of polymerization and different systems exist to categorize them."
"The complexity of polymerization reactions varies due to the functional groups present in the reactants and their inherent steric effects."
"Alkenes form polymers through relatively simple radical reactions."
"Reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize."
"Alkenes can polymerize to form compounds such as polyethylene and polyvinyl chloride (PVC), which are produced in high tonnages each year."
"Polymers such as PVC are referred to as 'homopolymers,' as they consist of repeated long chains or structures of the same monomer unit."
"Polymers that consist of more than one monomer unit are referred to as copolymers."
"Monomer units such as formaldehyde hydrates or simple aldehydes can polymerize themselves at quite low temperatures to form trimers."
"Trimers can cyclize to form ring cyclic structures or undergo further reactions to form tetramers."
"Small polymers are referred to as oligomers."
"Formaldehyde allows nucleophilic addition of hemiacetal intermediates, which react with other non-polar molecules present to form more stable polymeric compounds."
"Autoacceleration is a phenomenon where polymerization proceeds at a fast rate and can be very hazardous."
"Autoacceleration can cause fires and explosions."
"Alkanes can also be polymerized, but only with the help of strong acids."
"They are produced in high tonnages each year due to their usefulness in manufacturing processes of commercial products, such as piping, insulation, and packaging."
"Homopolymers consist of repeated long chains or structures of the same monomer unit, while copolymers consist of more than one monomer unit."
"Reactions involving substitution at a carbonyl group require reactants that polymerize in a more complex manner."
"Formaldehyde hydrates and simple aldehydes are able to polymerize at low temperatures due to their exceptional reactivity as electrophiles."
"Nucleophilic addition of hemiacetal intermediates occurs during polymerization, which are short-lived and relatively unstable 'mid-stage' compounds."
