C11 Polymers Flashcards

1
Q

describe addition polymerisation

A

when alkene molecules join up to form polymers by
the double covalent bond between carbon atoms in each molecule opening up
and being replaced by a single carbon-carbon covalent bond
forming thousands of joint molecules
and the polymer as its only product.

Q

describe condensation polymerisation

A

when two different types of monomer join together by each of their different functional groups reacting with each other, forming a polymer and a small molecule

Q

how are polypeptides produced?

A

the condensation polymerisation amino acids, in which
their two functional groups react with one another
as one is basic (the amine) and the other acidic (carboxylic acid)
forming polypeptides and water
