Companion Planting with Herbs. Companion planting is simply utilizing the growth habits, natural insect attractant or repellent attributes and chemistry of companion plants to help each other grow and thrive. A companion plant might attract honeybees or repel cabbage flies.
The benefits of polymer additives in this study are shown to include improved shear stability, enhanced water resistance, and increased yield. Polymer additives are available in a variety of forms, including liquid, gel, powder and pellet, for ease of use.he benefits of polymer additives in this study are shown to include improved shear stability, enhanced water resistance, and increased yield.

Polymers are large molecules, a type of macromolecule. Their chemical properties are similar to those of simple molecules. For example, if the polymer contains a carbon-carbon double bond, as in poly(but-1,3-diene), it will undergo additions reactions with, say hydrogen or bromine.epending on the reactivities of the monomers, they may form polymers with different arrangements of the monomer units (Figure 2). SBS is an example of a block co-polymer. SBS is so named with S referring to Styrene (phenylethene) and B for Buta-1,3-diene. First, phenylethene is polymerized.
