Many people think of polymers simply as plastics used for packaging in household objects and for making fibres but this is just the tip of the iceberg Polymers are used in all sorts of applications you might not have thought much about before for ex performance polymers to improve the impact strength and aesthetic appearance of its polypropylene (PP) injection molded paint pails. Vistamaxx polymers also deliver better processability and cost per Kyle Douglas, James Farber, Steven Flynn, Janie Gu, . Vivian Qin, Jenny Shih, Jake . Silberg. , Anita . Wamakima.

Define polymers. Distinguish between addition and condensation as reactions in the formation of polymers. Name examples of polymers formed by:. C1.5. What do I need to know?. Recall. how hydrocarbons can be cracked to make smaller more useful molecules.. Describe. some of the properties of alkenes. Explain. how alkenes can be used to synthesise polymers for a wide range of different applications.. What is petroleum?. Also known as crude oil. It is a thick black sludge. It comes from ancient plant and animal life long since buried and kept under extreme pressure for millions of years.. It is composed of countless different organic compounds..
