Ques:Answer the following question given this paragraph: fibers, films, plastics, semisolid resins, and rubbers are also polymers. More than half the compounds produced by the chemical industry are synthetic polymers. Some common addition polymers are listed in http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch13_s05_t01. Note that all the monomers have carbon-to-carbon double bonds. Many polymers are mundane (e. , plastic bags, food wrap, toys, and tableware), but there are also polymers that conduct electricity, have amazing adhesive properties, or are stronger than steel but much lighter in weight. Table 13.2 Some Addition Polymers. Q: More than half the compounds produced by the chemical industry are what? Choices: - replacement polymers - artificial polymers - gas polymers - synthetic polymers A:

Ans:synthetic polymers
