Isotactic Polypropylene Research Paper

895 Words4 Pages

Chemical Structure of Isotactic Polypropylene Isotactic Polypropylene has a simple molecular structure. It contains a carbon ‘backbone’ chain whereby carbon is bonded to carbon atoms in a polymer chain, carbon is bonded to hydrogen atoms and methyl groups. (CH3). All the methyl groups are positioned on the same side of the chain, resulting in a regular and uniform structure of polymer. Polypropylene forms the head to tail structure through polymerization. There is strong covalent bonds between these atoms but weak Van der waals force (dipole-dipole force) between Polypropylene molecules. Isotactic Polypropylene forms a somewhat tetrahedral arrangement and its molecules are asymmetrical. These molecules form a long polymer chain. …show more content…

Part I Which of the concepts in these chapters was the most difficult for you? In 5-7 sentences, explain what you think you understand and ask 2-3 questions about things you know you don 't understand. Standard error of the mean I read the section on standard error of the mean (SEM) three times and unfortunately, this concept is difficult for me to understand. I do understand that the standard error of the mean is the standard deviation of a sampling distribution of means. I understand how to calculate the SEM (simply divide the standard deviation of the sample by the square root of the sample size minus one).
