In contrast to chain-growth polymers, most of which grow by carbon-carbon bond formation, step-growth polymers generally grow by carbon-heteroatom bond formation (C-O & C-N in Dacron & Nylon respectively). Polymer chemistry is a sub-discipline of chemistry that focuses on the chemical synthesis, structure, and chemical and physical properties of polymers and macromolecules.The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry, analytical chemistry, and physical chemistry. The ester functional group may be represented as -COOR. In other words, the reaction between carboxylic acids and alcohols which forms esters cause the formation of a polyester. A polymer, which is one of the fundamentals of artificial use of science, is quite an interesting aspect. The COMPLETE Guide to Polymers.

Polyester is produced with a long chain synthetic polymer with ester. Both fabrics are flame retardant, but nylon is stronger, while polyester is more heat-resistant. Polyesters are a class of polymers that consist of esters in their primary chain. The development of water is the by-product of this polycondensation process. In contrast to chain-growth polymers, most of which grow by carbon-carbon bond formation, step-growth polymers generally grow by carbon-heteroatom bond formation (C-O & C-N in Dacron & Nylon respectively). Nylon also tends to be more durable and weather-resistant, which is why it is more likely to be used in outdoor apparel or gear. His intention was to prepare molecules of known structure through the use of known organic chemistry and to "investigate how the properties of these substances depended on constitution."
