The employment application form that you use should have space allocated for candidates to provide detailed contact information for the people that they are using as professional and/or personal references as well as a section dedicated to the individual's work history.
Be able to explain why chemists are developing new types of polymers: a) polymers that dissolve. b) biodegradable polymers. Be able to explain environmental and economic issues related to the use and disposal of polymers.ou should be familiar with the idea that everyday items such as supermarket bags are made from polymers. You should appreciate why technology moves forward with the development of materials focusing on the very wide range of uses that polymers have in the 21st century, including health care.
POLYMERS. Polymers are substances whose molecules have high molar masses and are composed of a large number of repeating units. There are both naturally occurring and synthetic polymers. Among naturally occurring polymers are proteins, starches, cellulose, and latex.Synthetic polymers are produced commercially on a very large scale and have a wide range of properties and uses. The materials commonly called plastics are all synthetic polymers.Polymers are formed by chemical reactions in which a large number of molecules called monomers are joined sequentially, forming a chain. In many polymers, only one monomer is used. In others, two or three different monomers may be combined.he materials commonly called plastics are all synthetic polymers.
