Are the intermolecular forces between the chains in a Thermosoftening polymer strong or weak?
weak intermolecular forces
There are weak intermolecular forces between polymer chains in thermosoftening polymers.
What are the properties of Thermosoftening polymers?
Thermosoftening (also called thermoplastics) are plastics which will soften when heated and can be reshaped. Thermosetting plastics are plastics do not soften on heating. They are used when resistance to heat is important (eg kettles, plugs, laptop chargers etc).
What is the structure of Thermosoftening plastic?
Thermosoftening polymers are polymers that can be re-shaped into a new shape once they are heated up. Polyethylene is an example of a thermosoftening polymer. This includes both types of polyethylene polymers, high-density and low-density. High-density is a straight chain and is stronger.
Which force of attraction is present in thermosetting plastic?
Thermosetting polymers are formed by condensation polymerization. In this kind of polymer, the individual monomer units are bind by strong covalent bonds and form a three dimensional cross linked-network.
Why are Thermosoftening thermoplastic polymers soft and flexible?
Like the noodles, these polymers can slide over one another making these items made from them soft and flexible. In fact, these polymers can only interact by weak intermolecular forces and can, therefore, be separated rather easily when heated giving them relatively low melting points.
Why are Thermosoftening polymers soft and flexible?
Thermosoftening plastics do not have covalent bonds between neighbouring polymer molecules, so the molecules can move over each other when heated and the plastic melts.
What happens when a Thermosoftening polymer is heated?
Thermosoftening plastics melt when they are heated. Most plastics that we come across in everyday life are thermosoftening plastics. This means that they can be recycled , which involves melting them before making a new product.
What is present between polymer chains in Thermosoftening polymers?
Thermosoftening polymers [thermoplastic]: consist of individual, tangled polymer chains without cross-links between molecules. the polymer softens on intense heating-the heat breaks down the weak intermolecular van der Waals forces of attraction between the polymer chains.
Which polymer has strong intermolecular forces * thermoplastic thermosetting plastic elastomer plastic?
Here’s your answer!! Option (d) Thermosetting polymers is the correct answer. Explanation ➡ Thermosetting polymers are cross linked or heavily branched molecules which on hetaing undergo extensive cross linking in moulds and again become fusible. These have strongest intermolecular forces.
Which polymer has strongest intermolecular forces?
The polymer having strongest intermolecular forces is
- Neoprene.
- Polythene.
- Nylon-6.
- Buna-S.
