Structure has a strong influence on the other properties of a polymer. For example, a linear chain polymer may be soluble or insoluble in water depending on whether it is composed of polar monomers (such as ethylene oxide) or …

WebProperties of Polymers - Key takeaways. Different types of polymers have different properties depending on their structure and bonding. LDPE is branched and relatively flexible whereas HDPE is denser, stronger and formed predominantly of straight chains. Kevlar and Nylon are both polyamides and used for items such as clothing and ropes.
