What do Polymer Chemists Do?
The majority of natural rubber is produced in Asia, but it can also be produced in India, Africa, Central and South America. Using starting materials, i. In addition to aesthetics, coatings provide vital protection of the object from degradation by environmental factors, such as sunlight, moisture or oxygen.
A polymer can be an end product in itself, or it can be an ingredient that changes the properties of another product. Adhesives are used to produce the multi-layer films used in food packaging to extend shelf life, and they are a critical component of the tamper-proof packages, which ensure the safety of over the counter medicines.
It is sold as a commodity though traders. If you submit a manuscript after August 29,your work will be considered for publication in the merged title, Journal of Polymer Science.
For example, for PET, ethylene glycol produced from natural feedstocks can be used. Exposure of the mixture to UV light caused the PAG to generate an acid, which activated the catalyst and promoted ring-opening metathesis polymerization reactions. Major industries served include rubber and plastic products, textiles, apparel, petroleum refining, pulp and paper, and primary metals.
Sustainable agriculture has evolved to maximize land use and conserve natural resources and polymers, in the form of plastics, help this goal.
Synthetic rubber is produced by many companies around the world including Firestone, GoodyearLanxessMichelin, Zeon and hundreds of others.
