Financial Analyst Assistant Resume Sample Gel Permeation Chromatography ()Dilute Solution Viscosity Testing ()Melt Flow Index Testing ()Molecular Structure determines if a polymer is a homopolymer or a copolymer, for example Amount of Glue Borax Substitute PPR'S PPR'S Variables Amount of Glue (IV): We placed a cup on the electric scale then zeroed it. Define the following terms: polymer, monomer, repeat unit, crosslinking, biopolymer. We have multiple approaches for Polymer Characterization. Understanding the Mechanics of Golf Ball Impact: Using standard mechanical testing techniques to characterise materials for finite element analysis. Some instructors require a lab report to be included in a lab notebook , while Polymer Ball Lab Report others will request a separate report Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1. Glue contains the polymer polyvinyl acetate, which cross-links to itself when reacted with borax (diagram below). Other natural polymers are cellulose and starch. Amount of Glue Borax Substitute PPR'S PPR'S Variables Amount of Glue (IV): We placed a cup on the electric scale then zeroed it. This week we are exploring chemistry by making a polymer ball out of ingredients you probably have at home. Slime is made of two components. Course. The protein DNA, which is the “blueprint” for cellular reproduction, is a naturally-occurring polymer.

It may be necessary to let the polymer cool some to Polymer Ball Lab Report get just the right combination of viscosity and strength Melting point and glass transition temperature of polymer. • Silicones form very stable polymers and are. DISCUSSION: Polymers are extremely large molecules (molar masses from 1000 to greater than 106 g/mole) which result from chemically linking thousands of relatively small molecules called monomers The first synthetic polymer, a phenol-formaldehyde polymer, was introduced under the name “Bakelite”, by Leo Baekeland in 1909. The small molecular unit is called a monomer. Temperature can have a major effect on the value of the. The Bouncing Ball or “Bouncy Ball” is created by the reaction of two chemicals, ethyl alcohol and sodium silicate. Bouncy Ball; The Bouncy Ball Experiment Discussion. The Hands-on Plastics Kit has the different plastic resins specified for the Plastics Analysis Lab. Analysis User Manual Version 6.5. The cage molecule, polyhedral oligomeric silsesquioxane (POSS), is an inorganic nanomaterial that provides excellent thermal stability and mechanical property when incorporating into conjugated polymers Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1. Record the temperature shown by the thermometer for each ring and ball at the instant the sample surrounding the ball touches the bottom plate of the support, if any or the bottom of the bath.

English Essay Introduction Words For Shows The topic of this lab is confined to the tensile property of polymers. The plastic you made is an interesting type of polymer made up of chains of casein from milk. This test consists of two brass ring and two steel ball, using which the softening point of various bituminous materials are determined rate of 5 + 0.5 0 C per minute until the material softens and allow the balls to pass through the ring. Lab Report Requirements 1. A silicon polymer bouncy ball I made in my lab. TABLE A1.1. Strong synthetic polymers form fibers for clothing and other materials Superabsorbent polymer (SAP) materials are hydrophilic networks that can absorb and retain huge amounts of water or aqueous solutions. The kids may want to design a drop test to compare the three recipes. Mar 20, 2018 · Lab report engineering materials lab - tensile test 1. Below are specific labs for each type of polymer. Polymer Ball Lab Report

If the gum is somewhat brittle, continue kneading. Of course, it’s impossible to get it 100% exact, but you’ll be able to get a good estimate of how high the ball …. (b) To follow the kinetics of polymerization by monitoring the variation of. 3. Other natural polymers are cellulose and starch. Each monomer is incorporated into the polymer is known as a repeat unit or monomer residue.. This week we are exploring chemistry by making a polymer ball out of Polymer Ball Lab Report ingredients you probably have at home This baking soda and vinegar powered boat was such a fun way to build and explore movement powered by science. A polymer is a long chain of hundreds or thousands of tiny molecules. In doing the reactions, I was able to show the way an ester looks once the alcohol and carboxylic acid react in the form of a skeletal structure Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1. Rayon, the first synthetic fiber was developed as a replacement for silk in 1911 Polymer chemists study large, complex molecules (polymers) that are built up from many smaller (sometimes repeating) units.
