Which of the following best describes "homopolymer tails" as they relate to recombinant DNA technology? Monomer a small molecule which may react chemically to link together with other molecules of the same type to form a large molecule called a polymer. Showing your customers the differences between the two grades might help you to justify the higher price of homopolymer. Filed Under: Polymer Chemistry. Typically, chlorine and PVC react according to a basic free radical mechanism. Amylose is insoluble in water and is harder to digest than amylopectin (see below). Ethene, homopolymer.

Polyacetals are subject to oxidative and acidic degradation, which leads to molecular weight decline. SCG HDPE is a high-density polyethylene resin produced by a bimodal process, a technology developed by Mitsui Chemicals Inc. of Japan. Some thermoplastics, besides being available in various flow rates, can also be found with the homopolymer or copolymer chain option, where homopolymer is the plastic resulting from the polymerization of a single monomer while the copolymer is that resulting from the polymerization of two or more monomers. : 26099-09-02. Acetal homopolymer is one type of acetal.

It has a high strength/weight ratio and is more rigid than the copolymer. However, the use of monomers, which may lack adequate homopolymer mechanical strength, as hydrophobic diluent comonomers in dental resins appears quite promising. The Substance identity section is calculated from substance identification information from all ECHA databases. Poly(I:C) is structurally similar to dsRNA, present in some viruses, and is therefore commonly used to model the actions of extracellular dsRNA.

2003) The model used here only involves the kinetic part with propagation and transfer to hydrogen. Polystyrene is composed only of styrene -based repeat units, and is classified as a homopolymer.
