Many of them are made partially or completely of polymers, both natural and synthetic. The questions this week will help you find out more about these important products. Explain how Charles Macintosh made what is probably the first man-made composite using polymers. Describe how the fiber and matrix work together to make a better product than either polymer alone. The questions this week are about some of these products.
Synthetic fingernails are extremely popular with women of all ages.
Polyacrylates are found in many very useful products. What are at least three uses of polyacrylates. We have already discussed Kevlar and linked three dimers made with our model kits to get an idea of what the structure of Kevlar looks like. In discussions of the market success of PVC or PP, for instance, only the polymers are usually mentioned, and little credit is given to the different additives that contribute to the wide range of properties, and thus the uses, that characterize these polymers. The questions this week, therefore, are about these additives.
