What are the names of reactions that build monomers into polymers and break down polymers into monomers? What are three types of organic polymers that are important to life? Answer of the following question. What process makes monomers into polymers?
Polyester is a specific type of polymer used mainly in fabrics and textiles, offering durability and chemical resistance, while polymers are large molecules comprising many repeated subunits, utilized across diverse industries.
Biodegradability, in the context of plastics and polymers, refers to the material's ability to break down into natural substances such as water, carbon dioxide, and biomass through the action of naturally occurring microorganisms. For Polylactic acid (PLA), this process is not just theoretical but...
Most polymers commonly referred to as plastics or thermoplastics consist of molecule chains that can be broken and re-bonded. Most common plastics can be bent into new shapes by applying heat. They also can be recycled. Plastic soda bottles, for example, can be melted down and reused to make...
What are the names of reactions that build monomers into polymers and break down polymers into monomers? What is the covalent bond between the carboxyl group on one amino acid and the amino group on the next, formed by a dehydration reaction?
developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the...
Recent innovations are exploring ways to make thermosets more recyclable, including chemical recycling methods that break down the polymers into monomers that can be reused. 4 How are thermoplastics recycled? Thermoplastics are recycled by melting them down and reshaping them into new products, a proce...

This acrylic fiber variant is composed partially of acrylonitrile, but a variety of other polymers are also used in its production. For instance, modacrylic contains a high degree of vinylidene chloride As such, fabrics made from modacrylic fiber generally have better drapability, wrinkle-resistance,...
These polymers are then melted down and stretched into thin films, which are then cut and sealed into bags. 三、Impact on the Environment Plastic bags have a significant impact on the environment. They are non-biodegradable, meaning they do...
