Propyl methacrylate nitrile (MAPA) is an important organic chemical raw material, which is widely used in polymer synthesis, coatings, adhesives and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of propyl methacrylate nitrile mainly include the following aspects:

upstream products:

1. Acrylonitrile: Acrylonitrile is one of the main raw materials of propyl methacrylate nitrile, which is produced by the oxidation of propylene.

2. Methacrylic acid: Methacrylic acid is another important starting material and is produced primarily by the reaction of ketene and methanol.

downstream products:

1. Polymer: Propyl methacrylate nitrile can be used as a monomer to generate polymers through polymerization, such as polypropyl acrylate, polypropyl methacrylate, etc. These polymers have good chemical resistance, heat resistance, weather resistance and other advantages, widely used in coatings, adhesives, plastics and other fields.

2. Copolymer: Propyl methacrylate nitrile can be copolymerized with other monomers to produce copolymers of various properties. For example, a copolymer excellent in impact resistance can be obtained by copolymerization with styrene, and a copolymer excellent in water resistance can be obtained by copolymerization with ethyl acrylate.

3. Modifier: Propyl methacrylate nitrile can be used as a modifier and added to other polymer materials to improve its performance. For example, it can be added to rubber to improve its oil and chemical resistance.

In short, propyl methacrylate nitrile has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive, which plays an important role in promoting the development of the field of polymer materials.
