A polyolefin is a type of polymer produced from a simple olefin (also called an De flesta elastomerer är termosetter, men TPE är termoplast.

Polymers with microcrystalline regions are generally tougher (can be bent more without breaking) and more impact-resistant than totally amorphous polymers. [42] Polymers with a degree of crystallinity approaching zero or one will tend to be transparent, while polymers with intermediate degrees of crystallinity will tend to be opaque due to light scattering by crystalline or glassy regions. 2016-12-08 · Polymers that contain built-in mechanisms for controlled degradation can be triggered by external stimuli such as ring strain, the α-effect, and pH and redox triggers, to name a few. Concurrent with the development of depolymerization catalysts and new recyclable materials, mechanical sorting methods in recycling plants and decontamination processes must continue to be improved. One such polymer, polyethylene terephthalate (PET) is a major part of the world's synthetic plastic production (33 million tons in 2015). 3–5 Unfortunately, the combination of the slow natural degradation of PET in the environment and poor disposal management has contributed to the global issue of plastic pollution.

Polymers are constructed from relatively small molecular fragments known as monomers that are joined together. Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times.

The transparency or translucency of plastics depends on the type and structure of the polymer/crystallinity and types of additives, fillers, colors, etc. used. Susceptibility to photo-oxidation varies depending on the chemical structure of the polymer.

Polymers display a wide range of chemical structures, thus making the depolymerisation of plastic waste a technically difficult task that is complicated further by the waste streams being mixed. In addition to that, plastic products usually contain several additives, such as plasticisers, dyes, or fibres, to improve their performances or reduce their cost, which further complicates their recyclability. Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1.

The course also includes some exercises to test your progress. Thermoplastic polymers can be very broadly classified as amorphous or crystalline. Most thermoplastics suitable for use as matrices for high performance composite exhibit some degree of crystallinity because this type of structure has better resistance to chemical attack by field, hydraulic oil and paint stripper. The raw material for manufacturing plastic products is called a resin. Some of the most common resins are polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). These resins are often used in packaging.

Polymers Index The polymer is a long chain molecule which is formed by joining many small molecules called monomers. Addition polymers are a type of polymer in which all the monomers are unsaturated or to simply to say are alkenes. During the polymerization process, the double bonds in the alkenes break and they all join together to form a large molecule. Corrosion by chemical reaction changes the configuration of the polymer chains. Listed below are some of the environments that causes chemical reactions in polymers.
