WebPolymers are large molecules made up of atoms joined together by strong covalent bonds. The intermolecular forces between polymer molecules are much stronger than in small molecules because the molecules are larger. This is why most polymers are solid at room temperature. Giant covalent structures WebThese polymers are found both naturally and synthetically made, and largely consist of ester, amide, and ether functional groups. Their properties and breakdown mechanism are determined by their exact structure. These …

More complex polymers form strong bonds, and hence, they are strong enough to withstand high force and pressure. Electrically conductive polymers are used in making electrical devices. how often to feed a small dogWebPolymers are generally considered flexible where the persistence length is one of the most important characteristics representing stiffness or flexibility. The persistence length equals to the average projection of the end-to-end vector on the tangent to the chain contour at a chain end in the limit of infinite chain length [15]. mercedes benz selling priceWebYour students will gain a deeper understanding of Ceramics, Polymers and Composites with our range of secondary science resources.
