A process is provided for the incorporation of fibrous material into a polymer wherein the fibrous material as a dispersion in water is added to a solution of the polymer which is being subjected to agitation, whereby the fibrous material transfers from the aqueous phase to the polymer solution...
During this process, the hydrogen in one monomer combines with the oxygen in another monomer to create water (H2O), which is secreted as a by-product – hence the “condensation” appellation. Due to the monomer shedding part of its original constitution, the polymer will have less mass than...
How To Sew Spandex Fabric Using polyurethane research, DuPont sought to create a new polymer fabric with high elasticity. During the development process, scientists at DuPont referred to this fabric as "spandex;" once this fabric was completed, it was sold under the brand name Lycra, but consu...

Unlike other types of fabric, polyester mesh does not get bogged down with sweat, and it is highly breathable. • Nylon mesh: One of the most iconic applications of nylon mesh is in beekeeping veils. This type of mesh is less commonly used to make apparel, and it is more frequently ...
This is particularly true in cases where the material is a reaction byproduct or degradant from the polymer synthesis. Considering these reasons, a number of different strategies should be applied to quantitate the components identified in an E&L study. Based on experience, two main methods are ...
Several nanoparticle systems have been used to aid in the formulation, encapsulation and release of active compounds extracted or derived from natural resources. The main types of these particles are liposomes, solid lipid nanoparticles, inorganic nanoparticles, micro-emulsion, polymer nanoparticles, dendri...
How would you expect the c r y s t a l l i n i t y of a p o l y m e r to be affected by the addition of a p l a s t i c i z e r ? A. Because the plasticizer is a molecule that fits between the main polymer chain...
Some gardeners start tubers indoors in containers a month ahead to get a jump on the season. Medium- to dwarf-size dahlias will do well in containers. How to Plant Dahlias Avoid planting dahlia tubers that appear wrinkled or rotten. Pink “eyes” (buds) or a little green growth are go...
referred to as an array, so that many reactions can be processed in parallel. The array fits into an instrument called a genetic analyzer, which provides the voltage, temperature, buffer, and polymer required for electrophoresis, and holds 96-well plates...
