28 Oct 2019 A new type of polymer designed by MIT chemists incorporates a special This new building block, or monomer, forms chemical bonds that can be the new monomers to industrial resins, such as plastics or adhesives.


Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1. To make recycling of these polymers easier, the plastics industry has adopted the codes shown. Since compliance in labeling is voluntary, not all plastics are labeled for identification. Identification, simply by

Betegnelsen stammer fra det græske “polymeros”, der kan oversættes til poly = mange og meros = dele. En polymer er derfor et meget stort molekyle – et såkaldt makromolekyle – sammensat af mange ens byggestene. 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).

Natural rubber is from the monomer isoprene (2-methyl-1,3-butadiene), which is a conjugated diene hydrocarbon as mentioned above. In natural rubber, most of the double fonds formed in the polymer chain have Polymer.

The term inorganic polymer refers generally to one-dimensional polymers, rather than to heavily crosslinked materials such as silicate minerals. The formal definition of a thermoplastic rubber or elastomer (TPE) is “a polymer blend or compound which, above its melt temperature, exhibits a thermoplastic character that enables it to be shaped into a fabricated article and which, within it’s design temperature range, possesses elastomeric behaviour without cross-linking during fabrication. Keyflex® BT 1028D by LG Chem is a general purpose, compounded polypropylene grade reinforced with 10% talc.

In polymer science, thermosetting plastics and thermoplastics are plastic polymer compounds. Thermoplastic polymers are compounds that can be recycled by heating and moulding. If a sufficient temperature is provided to thermoplastic polymers, the material can be melted, placed in a mould and cooled to get a new article.

A monomer is a molecule that can be bonded to other identical molecules. Polymers are basically enormous molecules made with a massive amount of smaller, identical molecules.
