When heated due to the absence of cross links, they become free to move and and can be moulded into any desired shapes. 3 227 facile and fast two-s tep route compos ed o … http://www.csua.berkely.edu/~ranga/school/me223/nylon.gif, http://www.openlearn.open.ac.uk/course/view.php?id=2937, http://www.britanica.com/EBchecked/topic/468696/polymer, http://www.polymertalk.com/history_of_polymers.php, http://en.wikipedia.org/wiki/branching_%28chemistry%29, http://www.polymertalk.com/classification_of_polymers.php, http://docs.google.com/viewer?a=v&q=cache:Wbn5XOJDt:www.cmse.ed.ac.uk/MSE3/Topics/MSE3-polymers.pdf+intoduction+of+polymers&hl=en&gl=in&sig=AHIEtbQ22RNSIoIyoXUP9HtDd-nakz-w, http://www.cem.msu.edu/~reusch/VirtualText/polymers.htm. No plagiarism, guaranteed! When amide monomers are connected together by peptide bonds to form polymers, it is known as a polyamide. The sulphur bridge in this figure prevents the slip of the chains and rubber can be stretched to a limited extent and when tension is removed the chains try to coil up regain its original shape. The polymer so formed is called a polyacrylate whose swelling capacity and gel modulus depends greatly on the quantity and type of cross-linker used. These are used in making boat hulls, pass anger and naval vessels, gas masks, life boats. Free resources to assist you with your university studies! Registered Data Controller No: Z1821391.

The microstructure of a polymer (sometimes called configuration) relates to the physical arrangement of monomer (which I have explained above) residues along the backbone of the chain. This polymer may be more expensive than others however its resistance to chemicals results in a more durable and long-wearing product. Polymers in the natural world have been around since the beginning of time. It is a thermoplastic polymer and its plasticity can be increased . All polymers can be divided into two major groups based on their thermal processing behavior. The application of polymers are divided into various types of fields: Agricultural field: Mulching films, green house films are the best examples for the polymer films. it is prepared by heating vinyl chloride in an inert solvent in the presence of peroxides (eg.dibenzoyl peroxides).It isa hard horny material.

Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. With elaborately designed macromolecular structure, this material is … Another application of polymers is the long strands known as fibers. These are called polyhalo-olefins because they are derived from halogen substituted olefins. Rubber was named by the chemist Joseph Priestley who found that a piece of solidified latex gum was good for rubbing out pencil marks on paper. Many of the useful properties of polymers are in fact unique to polymers and are due to their long chain molecular structure. It was invented by Charles Goodyear in 1839.The formation of cross links formed at the time of vulcanization at the reactive sites makes rubber hard, tough with greater tensile strength. It involves a addition reaction in which one double bond in isoprene open to form a new bond with next unit forming a large chain. A chemical reaction of sulfur (or other vulcanizing agent) with rubber or plastic to cause cross-linking of the polymer chains; it increases strength and resiliency of the polymer chemically; the process involves the formation of cross-linkages between the polymer chains of the rubber’s molecules. Applications of conducting polymers: 1.
