Met behulp van de video's van sc Don't be misled by chemical formulas that depict polymers such as polyethylene as reasonably straight chains of substituted carbon atoms. Free rotation around C—C bonds allows long polymer molecules to curl up and and tangle very much like spaghetti (Figure \(\PageIndex{2}\)). Thus polymers generally form amorphous solids. Thermosetting polymers normally are made from relatively low-molecular-weight, usually semifluid substances, which when heated in a mold become highly cross-linked, thereby forming hard, infusible, and insoluble products having a three-dimensional network of bonds interconnecting the polymer chains (Figure 29-2). 2019-12-05 · The term polymer is commonly used in the plastics and composites industry, often as a synonym for plastic or resin.
