Polymerization

Experiment #6 Polymerization Polyamide and Polyurethane synthesis CHEM 311: Organic chemistry Laboratory 2 Section 3: Wed. 2:00p.m.-4:50p.m. Jonathan Thompson And Sarah Specht 4/17/10 Abstract: In this lab polymers was study and formed. Polyurethane implication was performed by coalesce diisocyanate and polyhydroxyester to make a cupcake. Nylon 6,10 synthesis was performed by pouring 1,6-hexandiamine into a beaker first and then adding sebacoyl chloride to make nylon rope. grounding: Polymers argon really large molecules, built from smaller molecules called monomers. Polymers give a quality orbit structure consisting of multiple reduplicate units that are tie in chemically. dissimilar repeat units result in a copolymer, extremely complicated. Some copolymers are biopolymers such(prenominal) as proteins and DNA that are formed for specific results to serve the purposes of the organism. thither are many another(prenominal) ways copolymers give the ga te be sequenced on the backbone: jump Copolymers, Block Copolymers, Random Copolymers, and Graft Copolymers. Different techniques are use to synthesize these polymers, and there are assorted overall structures, such as linear, branched, and cross linked.

Step-growth and chain-growth polymerizations are cardinal different techniques that can be used to make nylons. In step-growth polymerization, the monomers, which is the starting reagent, go and grow to form dimers, trimers, tetramers, and etc.. When this polymer reaches superior conversion, the monomers would gain been converted to in high spirits molecula r burden polymers. Chain-growth polymers fo! rm high molecular weight polymers much quicker than step-growth polymers. Growing polymer chain grows so unshakable that it does not spend much m as a oligomer (long chain, but not polymers, between 10 and 100 chain length). Another way to describe polymerizations is polycondensations and polyaddition. Polycondensations are polymerizations in which a small molecule by-product is formed. Polyadditions are...If you indispensability to get a full essay, order it on our website: OrderCustomPaper.com
