What is a polymeric molecule?

What is a polymeric molecule?

Polymer molecules, or macromolecules, are composed of large numbers of linked, small repeat units. The units from which polymers are synthesized are called monomers. Polymers may be made from one kind of monomer, giving homopolymers, or from several kinds of monomers, giving copolymers.

Are materials made of long repeating chains of molecules?

Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids. The formation of polymers, long-chain molecules made of repeating units of monomers…

Are made up of lots of small molecules joined together called monomers?

A polymer is made up of a number of joined-together monomers. One way of thinking about polymers is like a chain of connected-up paperclips. A polymer is a large molecule made up of smaller, joined-together molecules called monomers.

What is a monomer and a polymer?

Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.

Can a compound be formed from two simpler materials?

For each material, decide whether it is an element, a mixture or a compound. Then tick the box. There was a chemical reaction when it was formed from two simpler materials. It is made from atoms that are all the same. It cannot be broken into a simpler form.

What kind of material are atoms and molecules?

Atoms and molecules. Look at the table below. There are some statements and some materials . For each statement, decide whether it describes an element, a mixture or a compound and tick the box. For each material, decide whether it is an element, a mixture or a compound. Then tick the box.

What makes up the building blocks of all materials?

Atoms are the building blocks of all materials, no matter how simple or complicated the material is. An element is made up of only one type of atom. Compounds are made up of different types of atoms combined together. A lump of copper is made up of only copper atoms. Water particles are made up of hydrogen atoms and oxygen atoms combined together.

How are polymer chains linked in thermoplastics?

The polymer chains in thermoplastics are linear or branched and do not become cross-linked as in the case of thermosets.
