प्रश्न
Answer the following.
What are synthetic resins? Name some natural and synthetic resins.
उत्तर
- Synthetic resins:
These polymers are artificially prepared by polymerization of one monomer or copolymerization of two or more monomers.
e.g. nylon and terylene.
Synthetic polymers are further divided into three subtypes: fibres, synthetic rubbers, and plastics.
- Natural resins: Natural rubber, silk, wool, etc.
- Synthetic resins: Nylon, terylene, neoprene, etc.
