Cite five important characteristics for polymers that are to be used in thin-film applications that are used to protect printed wiring boards from environmental influences. a) low flexibility O b) resistance to moisture/chemical attack c) high gas permeability d) high tensile and tear strengths e) low density f) low gas permeability Og) high density o n) high flexibility
Discuss five polymers not covered in class that incorporate main group elements into the polymer backbone. Give reaction schemes, polymerization conditions, physical properties of the resulting materials and potential applications. *Any polymers are acceptable, ignore the comment about it not being covered in class
Solubility parameters (5) have developed to characterize miscibility of polymers with various solvents in applications from paints to coatings to membrane permeation. And, predicting the solubility of a polymer in a given solvent is one of the most important aspects of the use of solubility parameter data. describe how the selection of a solvent might depend on the molecular weight of a given polymer and the temperature at which the solvation takes place.
i) Which of the following is not true about step-growth polymers? Formation of step-growth polymers usually results in the loss of a small molecule. Step-growth polymers are formed by the reaction of bifunctional molecules. Step-growth polymers can be formed by a free radical mechanism. Step-growth polymers are also known as condensation polymers. Step-growth polymers do not reach high molecular weight until the reaction has gone nearly to completion. ii) Which of the following are not termination methods in radical polymerization?...
Write about Linear Programming Applications and use the 5W’s (Who, What, Why When, Where) and the How you plan to apply the Management Science and Analytics topics in your future career paths.
4. Glencoe Corp. is a small manufacturer of polymers used in specialized manufacturing applications. Glencoe’s first quarter income statement includes the following information: Glencoe Corporation First Quarter Income Statement Sales $1,238,400 Cost of Goods Sold $598,590 Gross Margin $639,810 Expenses Marketing expenses $211,730 Other General and Administrative Expenses $329,400 Total Expenses $541,130 Profit (Loss) $98,680 Glencoe is planning a promotional campaign in the second quarter to increases sales (marketing expenditures will return to first quarter spending after the second quarter)....
Which of the following statements about polymers is/are correct? select all that apply. Condensation polymerization reactions produce small molecules, like H2O, as byproducts to the polymer formation Addition polymers must be made from monomers which have at least one double or triple bond somewhere in the molecule. Polypropylene and polyethylene are high molecular weight alkenes.
(b) Write down two applications of supervised learning. In the two applications, state the target variables.
Which of the following is not considered true for polymers? O A. Polymers are transparent. O B. Polymers are recyclable. O C. Polymers are light and also hard to break. OD. Polymers are cheap and long-lasting. O E. Polymers can be easily processed to form various shapes.
