Enumere por lo menos 5 objetos que antiguamente se hacían con otro material y en la actualidad se hacen con un polímero. Identifique de qué polímero se trata.

Translation: List at least 5 objects that were formerly made from another material and are now made from a polymer. Identify what polymer it is

Five object now replaced with polymers

1) automobile body parts. (polypropylene, polyurethane and PVC)

2)TV cabinets. (polystyrene polymer)

3) composites for golf clubs. (carbon fibre reinforced polymer CFRP)

4) fibers for clothing and carpet. (acrylic and nylon)

5) foams for coffee cups (polystyrene)

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
