Polymer definition gcse
WebThe word polymer is derived from the Latin words poly, meaning many, and mer meaning parts. Polymers are long chained molecules formed by joining together many small reactive molecules called monomers ( mono and mer, meaning one part). Polymers are macromolecules due to their very large sizes and high molecular masses. WebPolymer: Definition: It is a polymer with very weak intermolecular forces and Viscoelasticity. Thus, they are famously known as elastic polymers. Is a macromolecule or large molecule made up of clusters of subunits. Physical property: They inherit the unique property of elasticity. They inherit diverse properties based on the category. Morphology
