Amylose ( CAS # 9005-82-7 ) is a linear polymer of glucose linked with mainly ? ( 1?! 4 ) bonds.
12.
Linear polymers are created using monomers with two reactive end groups and monomers with more than two end groups give three-dimensional polymers which are crosslinked.
13.
In general linear polymers are the most useful, but it is possible to introduce branches in nylon by the condensation of dicarboxylic acids with polyamines having three or more amino groups.
14.
The next major advance was the release in 1995 of the AB310 which utilized a linear polymer in a capillary in place of the slab gel for DNA strand separation by electrophoresis.
15.
Consider a linear polymer to be a freely-jointed chain with " N " subunits, each of length \ scriptstyle \ ell, that occupy distribution described by the formula
16.
Silver cyanide forms the linear polymer { Ag Ca " N?! Ag Ca " N?! }; silver thiocyanate has a similar structure, but forms a zigzag instead because of the sp 3-hybridized sulfur atom.
17.
Ring-opening metathesis polymerization of cycloalkenes can produce many important petrochemicals; this is of particular importance in an industrial capacity because synthetic capabilities include linear polymers from inexpensive monomers or polymers with special properties, thus compensating for an additional expense.
18.
The solubilization of prions is attributed to the polycationic and dendrimeric nature of the PAMAMs, with higher generation ( > G3 ) dendrimers being the most efficient; hydroxy-terminated PAMAMs as well as linear polymers showed little to no effect.
19.
The 1?! 4 linked starch part is called amylose and it is a linear polymer while the 1?! 4 and 1?! 6 linked part is the amylopectin, a branched chain polymer, being 1?! 6 the branching point linkages.
20.
The first protein to be sequenced was insulin, by Frederick Sanger, in 1949 . Sanger correctly determined the amino acid sequence of insulin, thus conclusively demonstrating that proteins consisted of linear polymers of amino acids rather than branched chains, colloids, or cyclols.
