Investigating the effectivness of PVA and PVAc as base polymers In the production of a polymer ball. Introduction A monomer refers to a specific group of atoms that from a molecular unit. When monomers are strung together like a long chain they form polymers. A good analogy of polymers‚ would be long connections of chains which become tangled like a bunch of spaghetti in a pot. The reason for experimenting with‚ and understanding polymers is because they play such a major roll and are found

temperature of different polymers 8.1 Compare and comment on the results obtained. LDPE has the lowest average melting temperature (103.6°C) out of the 4 polymers. It is because LDPE is a linear polymer that has a branched structure which is able to expel the applied heat faster through the “branches” and melt faster. HPDE has the second lowest average melting temperature (139.5°C) out of the 4 polymers. Unlike LDPE‚ HDPE does not have a branched structure and the HPDE polymer chains are able to pack

Project 1: Polymer Ball Vivian Kim General Chemistry 2045L Introduction Our assignment in this project was to create a bouncy ball for a company using polyvinyl alcohol (PVA)‚ polyvinyl acetate solid and sodium borate‚ by varying the ration of ingredients and to determine the best recipe for our bouncy ball. The company chose the materials because of their odorless and nontoxic properties. PVA is a water-soluble synthetic polymer and has adhesive properties

Sam Schuman 4/11/14 From Insignificant to Equal: The Evolution of Women throughout Winesburg‚ Ohio Gender roles have always played a crucial part in life. Throughout history the acceptable standard of behavior has been different for men and women and traditionally there have been different roles associated with each sex. In today’s society gender roles still exist‚ however; there is less disparity between men and woman and more of an equal balance between the sexes. This is in contrast

ELVAX 150W AND TOTAL HIPS 4440 POLYMERS ARE SAFE AND EFFECTIVE Our device’s Elvax® 150w and Total HIPS 4440 polymers provide a safe and effective product. HISTORY: Our oral device is made of two polymers‚ Elvax® 150w and Total HIPS 4440‚ used for a variety of purposes for decades. Since developing the first synthetic fiber--nylon--from research on large molecules called polymers‚ DuPont has remained a leader the field. In addition to Elvax®‚ DuPont makes high impact polystyrene (HIPS)

Terry v. Ohio 392 U.S. 1 (1968) The case of Terry v. Ohio is considered to be a landmark case because it is “understood to validate the practice of frisking (or patting down) suspects for weapons under diverse circumstances” (www.flexyourrights.org). These circumstances that allow for warrantless searches are applied only if and when an officer feels that peoples lives could be at risk‚ or if there is enough cause to believe that “a crime is in the process of being committed‚ a crime has already
