Big, complex molecules formed by the chemical joining of many smaller molecules. e.g. nylon.
compounds commonly used to bind styling products to the hair and sunscreens to the skin.
Long chains of chemicals, that can be twisted and molded into products. Petroleum is heated at very high temperatures to be broken down into polymers and made into plastic.
Long chain molecules such as PVC, nylon or DNA produced by the polymerisation of monomers.
long molecular chains (chain molecules) formed from monomers occurring as repetitive "building blocks" or monomer units in these chains ("polymer" is derived from the Greek word for "many parts")
Compounds of very high molecular weights that are made up of a large number of simple molecules which have reacted with one another.
Go to Materials & Technology Polymers are substances with high molar masses and are composed of a large number of repeating units (monomers).
Huge molecules formed through the repeated addition or condensation of many simple molecules.
Compounds formed by a reaction in which many small molecules (monomers) unite to form a larger or more complex molecule with a higher molecular weight and different chemical properties. Many polymers occur in nature, such as cellulose, rubber, silk and starch. A large number have been synthesized in laboratories and are commercially important products â€“ for example, nylon, polyesters, polyethylene and polyurethane.
Compounds formed by the joining of smaller, usually repeating, units linked by covalent bonds. These compounds often form large macromolecules (e.g., polypeptides, polysaccharides, nucleic acids, plastics).
Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule
Complex molecules with many individual parts, typically such as plastics or other complex absorbable molecules used in surgical treatment and implants.
a specific chemical component in the combination of chemicals that form the plastic that lenses are made from.
a special combination of chemicals that form the plastics from which contact lenses are made.
A high-molecular-weight organic compound, natural or synthetic, with a structure that can be represented by a repeated small unit, or mer.
Polymers are also mentioned frequently. Polymers are giant molecules with a repeating structure of smaller molecules called monomers. The most common polymers we see everyday are the various plastics. IF YOU CAME HERE FROM A DIFFERENT PAGE, CLICK ON THE BACK BUTTON TO GO BACK TO THE PAGE YOU WERE VIEWING.
Polymers, or plastics, are divided up into two main groups, thermoplastics and thermosets. See Thermoplastics and Thermosets.
A chemical compound or mixture that can use corn, corn starches and potatoes to make biodegradable packing fill, fast-food cups, lids, straws and cutlery. It is also being used as a biodegradable coating on fast food wrapping paper and paperboard containers.
Large molecules consisting of repeated chemical units (monomers) joined together. Examples of polymers: plastic materials, two-component glue.
