WebExamples of polymers include proteins, DNA, and plastics such as polyvinyl chloride (PVC) and polystyrene. We will focus here on these plastics, including polyamides, polyesters, and polymers made from alkenes, and the reactions that form them.These reactions are collectively known as polymerisation reactions. WebTHE POLYMERISATION OF ALKENES. This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as …
Webweek 11. The melting point of two compounds are as follows: Benzaldehyde's melting point is −26∘C and barium chloride's is 962∘C. Identify which are likely to be organic and inorganic compounds from these values. Benzaldehyde is more likely to be an organic compound because it has a low melting point. Barium chloride is likely to be ...
