Detailed explanation-1: -Addition polymers are made when alkenes molecules add together. The main polymer chain is made from carbon atoms bonded by strong covalent bonds. There are, therefore no polar bonds in addition polymers. This makes the polyalkenes inert and non-biodegradable.
Detailed explanation-2: -One of the useful properties of polymers is that they are unreactive . This means they are suitable for storing food and other substances safely. Unfortunately, this property makes it difficult to dispose of polymers. Most polymers, including poly(ethene) and poly(propene), are not biodegradable .
Detailed explanation-3: -To return to the question, the correct option is: “Addition polymers contain all of the atoms of the original monomers, but condensation polymers do not."
Detailed explanation-4: -Addition polymers are formed of chains of carbon atoms with strong C-H bonds and are resistant to biodegradation.
