The intrinsic viscosity for these molecules is equal to some constant times molecular weight raised to another constant according to the Mark-Houwink equation.
One synthesis for these molecules often uses MAO as a co-catalyst. The second virial coefficient for these molecules is zero at the theta temperature. The intrinsic viscosity for these molecules is equal to some constant times molecular weight raised to another constant according to the Mark-Houwink equation. Dynamic mechanical analysis of these molecules can be used to generate a plot of modulus versus temperature, which contains a knee at the glass transition temperature. The configuration of subsequent R and H groups determines the tacticity of these molecules. Very few branches are observed when they are synthesized from alkenes with Ziegler-Natta catalysts. For 10 points, name these long molecules made of small, repeating structural units that include polyethylene and polypropylene.
