A copolymer may include ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. Embodiments may also be directed to curable polymer compositions, expandable polymer compositions, articles, cured articles, and expanded articles formed from or including such copolymers of ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. A process for producing an ethylene vinyl acetate copolymer may include fermenting a renewable source of carbon to produce ethanol; dehydrating the ethanol, wherein the ethanol is dehydrated to produce ethylene; and polymerizing ethylene and vinyl acetate to produce the ethylene vinyl acetate copolymer.

An embolization system and methods for controlling solidification of embolic compositions comprising a first and a second embolic component that react with each other in vivo at a target site to form an embolic material, with the embolic components being dilutable in physiological fluids so that they do not form an embolic composition at a site that is not desired.

The present disclosure provides a method of preparing a vinyl chloride-based polymer having improved processability due to excellent blendability, and the vinyl chloride-based polymer having a particle non-uniformity of 10 or more defined by Equation 1. $\begin{array}{cc}\mathrm{Particle}\mathrm{non}\text{-}\mathrm{uniformity}\left[E\left(X\right)\right]=\frac{1}{50}\underset{i=1}{\overset{50}{.Math.}}{X}_i& \left[\mathrm{Equation}1\right]\end{array}$

The present disclosure provides a polymer composition. In an embodiment, an ethylene-based polymer composition is provided and is formed by high pressure (greater than or equal to 100 MPa), free-radical polymerization, by reacting: ethylene monomer and a mixture of hydrocarbon-based molecules, with each hydrocarbon-based molecule comprising three or more terminal alkene groups.
