Polymer degradation - Wikipedia

Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their production, use, disposal into the environment and recycling. The rate of this degradation varies significantly

Flock And Flocking - Understanding the Flocking process

The flocking process involves applying short monofilament fibres, usually nylon, rayon or polyester, directly on to a substrate that has been previously coated with an adhesive. The diameter of the individual flock strand is only a few thouhs of a centimeter and ranges in length from 0.25 - 5 mm. Adhesives that capture the fibres must have the same flexibility and resistance to wear as the substrate.

Crystic Composites Handbook | Scott Bader

It involves converting dicyclopentadiene (DCPD) to cyclopentadiene (CPD) at a temperature greater than 130ºC. The CPD is then grafted onto the resin backbone by reaction with a site of unsaturation. This can be achieved by an early reaction with maleic anhydride or at a later stage of the polymerisation process.

In the “one-shot” method, all the ingredients are mixed together; in the prepolymer method, the diisocyanate and oligomeric diol are allowed to react before the chain extender is added. Generally, the oligomeric diol and the diisocyanate are not miscible, so the reaction occurs at the interface between the two components, which can lead to large compositional variations over the course of the reaction.
