GCSE Maths Past Papers. Thermoforming polycarbonate is a manufacturing method that involves heating the plastic to a soft, flexible state, then fitting it around a custom mold or tool to create a desired shape. Early plastic is bakelite, or polyoxybenzylmethylenglycolanhydride. It was first developed in the mid-1930s by DuPont engineers, and has been used in almost every industry since then. AREA Rectangle: A, ft2 = L * W Circle: A, ft2 = 0.785 * D2 VOLUME Other Functional Skills KS3 Maths KS3 English KS2 KS1. ), Virtual Textbook of Organic Chemistry. Finally, we derive the massive scaling limit for the 2-point function of the one-dimensional hard-core gas, and thereby obtain the scaling form of the 2-point function for branched polymers in three dimensions. pdf, 39 KB. Scientists have been researching man-made polymers since 1832. The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. Jump to navigation Jump to search. Show All Hydrogen Atoms. PVC is a naturally thin, porous plastic, without the additives of plasticizers. Chemical also can be an adjective to describe properties of materials that are the result of various reactions between different compounds. PMCs are designed to transfer loads between fibers of a matrix. Free equations calculator - solve linear, quadratic, polynomial, radical, exponential and logarithmic equations with all the steps.

Polymer dosage, mg/L = (Polymer pumping rate, gpm) x (Polymer conc. The process of formation of polymers from respective monomers is called polymerization. 28 Silicone Polymer. If Y and Z represent moles of monomer and polymer respectively, Z is approximately \(10^{-5}\) Y. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Plastics are used for a wide variety of resources. Free. All Past Papers. The two open bonds remaining at the ends of the long chain of carbons (colored magenta) are normally not specified, because the atoms or groups found there depend on the chemical process used for polymerization. Starch, cellulose, and rubber all have polymeric qualities. It is usually formed into fibers that can be used in microfilaments and yarns. Required fields are marked *. Have questions or comments? Polymer is a material which is built up together with a large number of small recurring molecules called monomers. The characteristics that polymers exhibit are one major difference between polymers and small molecules (monomers). Bakelite is a trade name of the phenol-formaldehyde resin, which is one of the earliest synthetic polymers. A polymer matrix composite (PMC) is a composite material composed of a variety of short or continuous fibers bound together by an organic polymer matrix. This course includes operations with and conversions between fractions, decimals, and percents. Which one of the following is the chemical formula for the repeating unit in polyethylene: (a) CH2, (b) C2H4, (c) C3H6, (d) C5H8, or (e) C8H8? Polymer, any of a class of natural or synthetic substances composed of very large molecules that are multiples of simpler chemical units. chemical bonds Attractive forces between atoms that are strong enough to make the linked elements function as a single unit. HDPE is composed of macromolecules in which n ranges from 10,000 to … There are several different polyethylene forms, most of which are defined by the chemical formula (C2H4)n. Polyethylene is produced from ethylene typically obtained from petroleum or natural gas, … Polyvinyl chloride (PVC) after polyethylene and polypropylene, is one of the most commonly manufactured thermoplastic polymers in the world. B. Polystyrene also known as PS is a high molecular weight polymer produced from styrene. It is a complex molecule that contains genetic information which is stored in the order in which the bases organise themselves, which is a … [ "article:topic-category", "showtoc:no" ], information contact us at info@libretexts.org, status page at https://status.libretexts.org.
