Polymers 0.0 / 5 ? ChemistryPolymersGCSEEdexcel Created by: emilykeelingCreated on: 04-11-14 15:03 What is a polymer? A plastic 1 of 15 What are polymers made of? Hundreds of monomers that joins together to form long chains 2 of 15 What is a natural polymer? give an example. A natural polymer is a plastic formed naturally and not man-made. For example rubber, silk, proyein, DNA and starch. 3 of 15 What is a synthetic polymer? give an example. A synthetic polymer is a plastic that do not form themselves, but are man-made. For example kevlar, polyester, polystyrene, polyethene and nylon. 4 of 15 What is the name of the bond that join the monomers between atoms? The name of the bond that joins the momemers between atoms is a covalant bond 5 of 15 In a covalabnt bond, each atom shares something with another atom. What do they share? each atom shares one or more electrom with another atom 6 of 15 Many polymers are formed from alkenes. What is an alkene? An alkene is a hydrocarbon molecule 7 of 15 Polymers are formes form alkenes. What is the general formula for alkenes? Cn H2n There are twice as many hydrogens that carbons in an alkene 8 of 15 Alkenes contain at least one double covalant bond between carbon atoms. How does this double bond effect the reactivity? The double bond makes them very reactive 9 of 15 What is the name of the shorthand version of polymerisation? A catalyst is the name of the shorthand version for polymerisation 10 of 15 If all polystyrene foam cups produced in 1 day were all lined up, what is there enough to circle? There is enough produced in 1 day to circle the Earth 11 of 15 What oils are used to make most plastics? Fossil fuels 12 of 15 If a plastic item was recycled, how much more energy could it save than burning it in an incinerator? By recycling a platic item, it could save twice as much energy than burning it in an incinerator 13 of 15 There are 6 types of plasics. Name at least 3. PET, HDPE, PVC, LDPE, PP, PS 14 of 15 1 plastic bottles energy saved is enough energy to power a computer for 25mins or a 60w lightbulb for how long? 1 plastics bottles energy saved is enough energy to poer a 60w lightbulb for upto 6 hours! 15 of 15
