Making Plastics: From Monomer to Polymer | AIChE
The chemistry of making plastic. It’s helpful to understand some of the chemistry behind the polymerization reaction to appreciate how the process works and the complexity involved in making plastic. A polymerization reaction starts with a primary ingredient (monomer), such as ethylene or propylene. Ethylene (C 2 H 4) is a stable molecule
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticization Methods & Processing with Plasticizers There are two main principal methods exist for plasticization - Internal Plasticization and External Plasticization. Internal Plasticization A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.

This general purpose plasticizer for industrial applications is ideally suited to films and coatings. It is highly versatile and displays low viscosity. Other key features include its good low-temperature performance and low volatility. Plastomoll These are adipic acid-based monomeric plasticizers with good low tem-perature properties.
- How can plasticizers be used in industrial applications?
- External plasticization using low molecular weight plasticizers is the most widely applied approach in industrial applications. The glass transition temperatures and the mechanical properties (elastic modulus) of CA systems with different plasticizer contents are reported in Table 2.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
