2020-7-15As early as the 1860s, chemists were exploring ways in which naturally occurring polymers such as cellulose could be modified to make them more useful. These polymers eventually became known as plastics. The term comes from the fact that most early polymers could be
Sustainable development in construction is particularly important, as this branch of the industry is consuming enormous amounts of mass and energy. A new research area has been created by this idea
Consequently, diapers made from these materials were extremely bulky. More efficient absorbent polymers were developed to address this issue. Since the 1970s, disposable diaper technology has continued to evolve. In fact, nearly 1,000 patents related to diaper design and construction have been issued in the last 25 years
2018-1-313D printing construction is the future of the sector, and has already been demonstrated to be able to 3D print houses in just 24 hours. We examined the industry to find out everything to expect in 3D printing in construction in the future. Click here to find out more
Modacrylic and acrylic polymers have other characteristics that make them useful in fake fur manufacture. They are light-weight and springy, imparting a fluffy quality to the garment. They are also highly resistant to heat, sunlight, soot, and smoke, are strong and resilient, and show good stability during laundering
The premise of the question is that carbon is useful to polymers. I agree How is it useful to polymers Lets work backwards. Polyethylene PE is a synthetic polymer with the highest production volume, and its structure looks something like th
