Natural Polymer: Those materials that are produced naturally are known as natural polymers. Condensation polymerization or addition polymerization are the processes used to create these polymers.
DNA, cellulose, proteins, wool, silk, and wood are examples of naturally occurring polymers.
Wood: Natural polymers found in wood include lignin, cellulose, and different hemicelluloses.
The development of innovative wood-polymer hybrid materials has been supported by the utilization of wood, an abundant and natural source of organic polymers.
As the material that has been found in wood is a natural polymer so the wood can consider a natural polymer.
