WebThe polymerisation method can often determine the properties of the resulting polymer; Reaction condition in the polymerisation can have a big impact on a polymer’s ability to pack neatly; Altering reaction conditions can lead to high and low density polymers; Low density polymers are made at high temperatures and pressures WebAddition polymers are made from molecules containing C=C bonds. Polymers have different uses that depend on their properties. DNA, starch and proteins are biological polymers.
