Polymer Chemistry

Polymer Chemistry is the examination of chemical properties of polymers and its applicability in the synthesis of new macromolecules. A polymer by definition is a large molecule composed of many subunits known as monomers. Polymers can either be synthetic or natural. Synthetic polymers include synthetic plastics such as Poly(1-phenylethane-1,2-diyl), also known as polystyrene, which is made up of styrene monomers. Natural polymers include proteins within the body, which are made up of amino acid monomers. Recently, there has been a major focus on the field of Polymer Chemistry due to the vast range of properties that polymers may inherently possess. Thus, combining different monomers/polymers to form macromolecules with novel properties may play an essential role in the innovations of science and technology. The applicability of Polymer Chemistry extends into the subjects of biology, physics as well as engineering. For example, Polymer Chemistry may be used to treat physiological conditions such as coeliac disease, which involves an abnormal digestive enzyme activity. By linking certain polymers to these abnormal enzymes, the researchers were able to normalize the enzymatic activity (1). Thus, these new polymers were designed to withstand the harsh conditions of the digestive tract in order to provide a therapeutic strategy for the treatment of coeliac disease. Although, Polymer Chemistry is nothing new, and has been done for years, new properties and new combinations of polymers are continuously being discovered to synthesize macromolecules with novel properties.

PMDA of polymer

Calculate the molarity of PMDA using the results of each standardization titration. Compute the molarity of PMDA from the mass of reagent used to make the PMDA stock solution. Compare these values and determine the percent purity of the solid reagent. Please provide steps with explanations. Results are in the Excel spreads

Cross-Linked Polymers

1. Why a polymer such as polybutadiene can be cross-linked, however a polymer such as polyethylene cannot be cross-linked. Please make reference to what it is about the chemistry of the repeating units that allows for the formation of cross-links. 2. Car tires are made of vulcanized rubber, which is a crosslinked polymer form

Polystyrene and Butene

1. POYSTYRENE: The monomer structure of polystyrene is shown attached. a) Would you expect polystyrene to be a stiff or a pliable polymer? b) What kind of synthesis is used in the production of polystyrene from styrene monomers? Addition polymerization, condensation polymerizaton or anionic polymerization? c) Calculate the d

Tacticity in Polymers

In the context of polymer science, what does the terms isotactic, syndiotactic and atactic signify?

Degree of crosslinking vs temperature for different polymers

Please explain to me how to sketch a graph of temperature against the degree of cross linking for the 4 types of polymers. Use the figure below to show how the four classes of polymers are related to each other. Your figure should be properly labeled to indicate the important mechanical properties associated with each polymer

Addition and condensation polymers

For addition and condensation polymers, in general, which kind of polymer, addition, or condensation , is likely to be less polar? Also, the less polar, the less able to adhere to water, so what are two polymers that would have virtually no tendency to adhere to water and why?

Hydrogen Bonding in Polymers With Alcohol Groups

I have attached 4 images for you to take a look at: 1) the chem structure of cellulose; 2) the chem structure of phenol-formaldehyde adhesive resin -- you will have to add NaOH to this structure since it is catalyzed with NaOH); 3) the chem structure of polymeric methylene diphenyl diisocyanate resin; and finally, 4) the chem st

Plastics, Hydrocarbons and Everyday Usage

1. PET is the most valuable plastic at the present time. Suggest a way to separate it from the others at a plastic recycling center. 2. Since waste plastics are mostly hydrocarbons, it has been suggested that waste plastic be used as fuel. From your observations, is this a reasonable suggestion. Defend your answer. 3. Su
