Compléter Polymers (D)Version en ligne Summary about polymers par Rosa Macchitella 1 Polymers are very large that are built up from a very large number of small molecules known as . Addition polymerisation occurs when an monomer , such as an alkene , bonds to itself in an addition . Poly ( ) , poly ( chloroethene ) and poly ( phenylethene ) are all addition polymers . polymerisation involves the loss of a small molecule ( usually ) in the reaction between two monomer molecules . Both polyesters and are formed by condensation polymerisation . Polyamides are formed by condensation polymerisation between an group and a carboxylic acid . These groups may be in the monomer or in different monomers . 6 , 6 is formed in a condensation between 1 , 6 - diaminohexane and hexanedioic . The numbers in the name of a particular nylon refer to the number of atoms in the monomers . Condensation polymerisation between the amino and carboxylic acid groups in amino acids produces a or protein . The amide links in these polymers are known as links .
