All are based on the chemistry of carbon, with its capacity for forming chains. The molecules that compose them (monomers) link together in the setting or curing process to form chains (polymers), which give plastics their flexible strength. Some plastics retain their ability to be softened ...

What monosaccharide is produced from the complete hydrolysis of amylose? What are the monomers and polymers of proteins? What are the three types of atoms that compose sugars and lipids? Which of the following is not a monosaccharide? A) Fructose B) Glucose C) Glyceraldehyde D) Galactose E) ...
Which of the following groups of people are the most severely affected by intense air pollutionA allergy sufferersB childrenC the old and illD asthma sufferers
This plastic is very lightweight and surprisingly lighter than even aluminum, which is the only more durable material used in luggage manufacturing. But when compared directly to polypropylene and even ABS plastic, polycarbonate is the heaviest of thermoplastic polymers. ...
. Fabric mills stretch out the pellets and join them together to form long strands of fiber. The fibers are combined to make a thread. The thread is then woven or knit into large rolls of fabric. While the production details are slightly different, the process is similar for both polymers...
Dedicated to spreading the Good News of Basic and Applied Science at great research institutions world wide. Good science is a collaborative process. The rule here: Science Never Sleeps. Another rule here: Scientists "invent" nothing. Instead scientists
Examples of other important thermoplastic polymers in which plasticizers are usually used are polyvinyl butyral (PVB), homopolymers and copolymers of styrene, polyacrylates, polysulfides, or thermoplastic polyurethanes (PU).The suitability of a substance for use as a plasticizer for a particular polymer...
