Acrylic Copolymer

What is an Acrylic Copolymer

The term “polymer” does not automatically mean a synthetic material. It basically means a combination of a large number of similar small molecules or “monomers” into large molecules or “polymers”. The polymer will have different properties to the monomer. There are a large number of naturally occurring polymers, these can be organic or mineral substances. Such natural examples of polymers include hair,  rubber, diamonds and sulphur. Even bitumen could be regarded as a polymer because of the long-chain nature of some of the organic molecules that are the constituent parts of bitumen.

Acrylic Copolymers are our green synthetic plastic adhesive compound of infinite repeating of molecular chains. These are polymers that have been manufactured in a chemical process to combine particular molecules in a way that would not occur naturally. And although various synthetic polymers have been capable of being produced since the early part of this century it is the more recently developed polymers that are now being used to modify bitumens and produce the “new” bituminous binders. The new polymers being the result of research and development by the large petro-chemical industries. But when I say “new” most of the synthetic polymers used in the modification of bitumen have been around for 30 years or more. What may be “newer” is the way that they are “mixed” / “blended” with the base bitumen.
