The temperature and pressure at which the polymerization occurs Polymers are very large molecules (sometimes called macromolecules). The properties of a polymer (or any other material) include strength, stiffness, hardness, density and melting point.. ... Recall that polymers are made from small molecules called monomers joined together in very long chains. In other polymers the branches become numerous and cross-link to other polymer chains, thus forming a network structure. Polymers are used in scores of industries for countless beneficial purposes, but no advances in polymer science are more striking than those in modern medicine. Polylactic acid, or polylactide (PLA) is a thermoplastic polyester with backbone formula (C 3 H 4 O 2) n or [–C(CH 3)HC(=O)O–] n, formally obtained by condensation of lactic acid C(CH 3)(OH)HCOOH with loss of water (hence its name).

This can be heated and bent using a line bender and, as it is a thermoforming polymer, it can then be reheated and reshaped. KS3 Polymers for the new national curriculum. Figure: 5 Example of a homologous series of alkanes with structure of CnH2n+2, Ivy Rose, (n.d) 2.4, 2.5 – As alkanes are saturate hydrocarbons, they are deemed unreactive due to containing single bonds such as C-H and C-C bonds which are quiet strong and difficult to break due to the strong intermolecular force. What are the Properties of Polymers?. The researchers have developed a novel technique that allows them to tag the creatures without the need for risky continual adjustments.
