Polyesters

• What are polymers made by condensation polymerization?

  Polymers can be made by condensation polymerization
• What does condensation polymerization usually involve?

  It usually involves two different types of monomers
• What happens to monomers during condensation polymerization?

  Monomers react together and form bonds
• How many functional groups must each monomer contain?

  At least two functional groups
• What can each functional group of a monomer do?

  It can react with another functional group of another monomer
• What is formed when functional groups react with each other?

  Long chains of polymers are created
• What is lost during the formation of each new bond in condensation polymerization?

  A small molecule, such as water
• What type of condensation polymers are polyesters?

  Polyesters are condensation polymers
• When do polyesters form?

  When dicarboxylic acid monomers react with diol monomers
• What do the blocks in the structure of polyesters represent?

  The rest of each molecule
• What do the dicarboxylic acid monomers contain?

  Two carboxylic acid (-COOH) groups
• What do the diol monomers contain?

  Two alcohol (-OH) groups
• What happens when the carboxylic acid group reacts with the alcohol group?

  It forms an ester linkage
• What is the result of the reaction between the carboxylic acid and alcohol groups?

  It forms an ester and releases water
• What is the significance of the ester linkages in polyesters?

  They connect the monomers in the polymer chain
• What happens when the carboxylic acid group reacts with another alcohol group?

  It forms another ester linkage
• What is the environmental impact of biodegradable polyesters?

  They can be broken down by bacteria
• What does the breakdown of biodegradable polyesters lead to?

  They decompose and reduce pollution
• What is the consequence of biodegradable polyesters not staying in landfills forever?

  They reduce the polymer's pollutant effect
• Are there any biodegradable polyesters mentioned?

  No biodegradable polyesters are mentioned
• What is the role of bacteria in the breakdown of biodegradable polyesters?

  Bacteria help decompose the polyesters over time
• What does the term "biodegradable" imply about certain polyesters?

  They can be broken down by living organisms
• What happens to polyesters in the environment over time?

  They decompose and do not persist indefinitely
• What is the effect of biodegradable polyesters on pollution?

  They help reduce pollution
• What is the significance of the statement "no biopolyesters here"?

  It indicates no biodegradable polyesters are discussed
