Which one of the following is an example of a thermosetting polymer?
As we discussed in concept
Thermosetting Polymers -
They are highly cross - linked, hard, infusible and insoluble polymers.They cannot be reused.
Eg:- Bakellite, Urea, Formaldehyde, Resin, etc
Phenol formaldehyde resin/ Bakellite/ Novolac -
- Obtained by the condensation reaction of phenol with formaldehyde.
- Step growth, Copolymer.
- Novolac is linear
- Bakellite is cross linked.
- Hard and brittle
- Novolac is used in paints.
- Bakellite is used in making combs, phonograph records, electrical goods.
Novolac and Bakelite are thermosetting polymer.
