Types of Polymers Natural polymers can be divided into two types based on their polymerization process - addition and condensation polymerization. Aspects of addition polymerization include:Examples of Polymers Lesson Summary Register to view this lesson Are you a student or a teacher? I am a ...
Thermoplastic polymersor thermosoftening plastics are the other type of synthetic polymers. While thermoset plastics are rigid, thermoplastic polymers are solid when cool, but are pliable and can be molded above a certain temperature. While thermoset plastics form irreversible chemical bonds when cured, ...
and occur either naturally or synthetically. Examples of natural polymers arecellulose, shellac and amber. Biopolymers such asproteinsandnucleic acids play crucial roles in biological processes. Common synthetic polymers are Bakelite, neoprene, nylon, PVC (polyvinyl chloride), polystyrene, polyacrylonitrile...
Types of Polymerization Mainly which process generates polymers are condensation and addition polymerizations. There are two types of polymerization based on their synthesis: addition polymerization and condensation polymerization, which generate different polymers. 1. Addition Polymerization:...
This lecture summarizes some of our recent results about reactions with synthetic polymers. By cationic ring-opening polymerization of 4H, 7H-1,3-dioxepin a linear polyacetal containing one C-C-double bond per repeating unit is obtained. Copolymerization of this monomer with trioxane or dioxolane ...
in which the molecular structure is a network, are thermosettingresins(i.e., they form under the influence ofheatbut, once formed, do not melt or soften upon reheating) that do notdissolvein solvents. Both linear and cross-linked polymers can be made by either addition or condensation polymer...
Condensation Polymers Math Worksheets A series of free IGCSE Chemistry Activities and Experiments (Cambridge IGCSE Chemistry). The following diagrams show Addition Polymerisation (Polyethene) and Condensation Polymerisation (Polyamide, Polyester). Scroll down the page for more examples and explanations....
Many organohalogen compounds, especially organochlorine compounds, are important industrial chemicals; they are used as solvents and pesticides and as intermediates in the preparation of dyes, drugs, and synthetic polymers. More than 2,000 organohalogen compounds have been identified as naturally occurring...
(PEG) chains to the system during the freeze-drying process. Further studies using other polymers, besides PEG, to achieve the same stabilization effect will be interesting. Thirdly, new materials are designed to obtain improved properties, such as derivatization...
