Difference between traditional organic polymer materials and new organic polymer materials

1. Traditional organic polymer materials: including plastic, rubber, fiber, film, adhesive and coating, among which plastic, synthetic rubber and synthetic fiber are called the three major polymer materials.

2. New organic polymer materials: polymers or polymers. A kind of macromolecules with multiple repeating monomer units, which are composed of one or more molecules or molecular groups (structural units or monomers) bonded by valence bonds.

Second, the structure is different.

1. Traditional organic polymer materials: During the long-term action of heat, light and oxygen, the polymer degrades, reducing its physical and chemical properties and mechanical properties. Completely disappear, even lose the use value. Therefore, it is often necessary to add anti-aging agents and other protective measures to extend the service life.

2. New organic polymer materials: Two or more polymers can be mixed by physical and chemical methods to make * * * mixed polymer alloys. For example, the impact toughness of plastic alloy mixed with nylon and polyolefin can be improved by more than 15 times. The alloying of polymers increases the freedom of material modification, and new materials with diverse properties and suitable for different working conditions can be prepared.

Third, the use is different.

1. Traditional organic polymer materials: meet the requirements of various special uses, including plastics, fibers, rubber, coatings, adhesives and other fields, and can partially replace metal and nonmetal materials.

2. New organic polymer materials: It plays an important role in promoting industrial and agricultural production and cutting-edge technology, and also plays an important role in exploring the mysteries of life, overcoming cancer and treating hereditary diseases.
