What is condensation polymerization GCSE?

In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers . This small molecule is often water. An example of a condensation polymer is nylon.

What is condensation reaction polymerization?

A condensation polymerization is a form of step-growth polymerization in which monomers and/or oligomers react with each other to form larger structural units while releasing smaller molecules as a byproduct such as water or methanol.

What is a condensation reaction GCSE?

Condensation polymers occur when a ‘double ended’ carboxylic acid forms an ester bond with a ‘double ended’ alcohol. This can happen with other functional group reactions also. Since there is a functional group at each end, it means that there can be a ester bonds can form at the beginning and end of each molecule.

What is a chain of monomers called?

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. a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.

What are examples of condensation polymers?

Examples of natural condensation polymers include cellulose, starch, and polypeptide chains of proteins. Several synthetic condensation polymers discussed include nylon, kevlar, polyester, Bakelite, Melamine, polycarbonates, polyurethanes, epoxies.

What are the examples of condensation polymer?

How are polymers made with condensation?

Condensation polymers are formed by the removal of water (or alcohols) during polymerization and the final molecular weight of the polymer is controlled by the equilibrium concentration of water or alcohols in the molten polymer at the end of the polymerization.

What does condensation mean in Chemistry GCSE?

Home > GCSE Chemistry > Synthetic & Naturally occurring Polymers. Condensation Polymerisation. Condensation polymerisation involves a reaction between monomers with two different functional groups. When these types of monomers react they join together, usually losing a small molecule such as water, and so the reactions are called condensation

Do You need A C bond in condensation polymerisation?

Condensation polymerisation – Higher. In addition polymerisation, the monomers must have a C=C double bond. However, in condensation polymerisation, the monomers do not need a C=C double bond but they do need two functional groups.

How are polyesters formed by condensation polymerisation reaction?

Polyesters can be formed by a condensation polymerisation reaction between a carboxylic acid monomer and an alcohol monomer if both monomers have two functional groups. A carboxylic acid with two carboxyl groups is referred to as a diacid and an alcohol with two hydroxyl groups is referred to as a diol.

How is hexanedioic acid used in condensation polymerisation?

Hexanedioic acid is a carboxylic acid with two carboxyl functional groups, hence the name dioic (di meaning two, and oic for the carboxyl groups). Polyesters can be formed by a condensation polymerisation reaction between a carboxylic acid monomer and an alcohol monomer if both monomers have two functional groups.
