X is thermoplastic whereas Y is thermosetting
X is thermosetting whereas Y is thermoplastic
Both are thermosetting
Both are thermoplastic
What is the name of the temperature above which a polymer is soft and flexible, but below which it is hard and brittle?
The melting point
The thermosetting temperature

Firstly, polymers are long chains which are made up of many molecules known as monomers. These monomers can be anything from amino acids, to alkenes, to alcohols. What all polymers have in common is the type of bond which holds their monomers together. What type of bond is this?
A metallic bond
An ionic bond
A covalent bond
A hydrogen bond
Polymers formed via addition polymerization are often used as plastics. The atoms/groups which make up the monomers determine the properties of the plastic. An example of this is polystyrene. Which monomers join together to form polystyrene?
Ethene
Chloroethene
Propanol
Phenylethene
When non-symmetrical alkenes polymerize (such as chloroethene - which makes up PVC), there 3 ways in which the groups can be arranged in 3-D space. For example, if all of the -Cl groups in polychloroethene (PVC) were arranged in the same direction in 3-D space, the polymer would be described as isotactic. What term is used to describe a polymer where the groups are arranged randomly?
Sporadic
Syndiotactic
Atactic
Practic
Write ZN Polymerization steps involved in its mechanism
