Polymer development industries are basically responsible in the development, discover, manufacture and distribution of specialty monomers. With their expertise on acrylates, fluorinated monomers, silicon-containing eyeglasses monomers as well as polymers and copolymers, an extensive datacenter of synthesis, protocols and formulations enable these companies to maintain up to date research and development efforts to the discovery and modern applications of specialty monomers.
Examples
Divinylbenzene, vinylbenzyl chloride, benzhydryl methacrylate are some examples of widely used specialty monomers. Divinylbenzene (DVB) is widely used in improving certain polymer properties to modify the utility eyeglasses online of adhesives, ion exchange resins, specialty plastics, elastomers and other common industrial items. Vinylbenzyl chloride (VBC) is usually homopolymerized or copolymerized through solutions, suspension, mass, emulsions and ionic techniques to chemically modify a particular product. Benzhydryl methacrylate is commonly used in manufacturing ophthalmic lenses requiring high refractive index. It is also used in making contact lenses as well as intraocular implants. This example of specialty monomer gives ophthalmic lenses a wide variety of attributes, which include hard, soft, water permeable and UV absorbing properties.
Applications
As the name implies, specialty monomers are created to serve a specific purpose, which basically aim to improve, modify, refine or add another attribute to a material or product.
For monomers or polymers intended for high temperature applications, a specialty monomer is used to give them exceptional thermal stability. It will prevent the occurrence of unwanted reactions when subjected to various range of temperatures.
Inhibition of divalent cation precipitation is an attribute given by a specialty monomer with strong sulfonic acids to completely ionize aqueous solutions. It is used to inhibit unwanted precipitation of divalent cations on the resulting polymer, which are commonly used on iron, aluminum and other metals.
A specialty monomer used is used to manufacture medical hydrogels to add lubricity or anti-coagulant characteristics on a solution. It is widely used in the manufacture of coatings for medical devices that usually comes in contact with tissue, blood and other biological fluids.
Specialty monomers are also used on personal care products such as the creation of homopolymer. Homopolymer is an efficient skin lubricant that is commonly used on hand lotions, body creams, soaps, shave and after-shave lotions, lip balms, cleansing creams and perfumes. It is also used in the manufacture of anti-wrinkle patches, blackhead removing patches or strips, facial cleansers and moisturizers.
Other applications for specialty monomers include coating and adhesive applications and acrylic fiber applications, which imparts a number of enhanced performance characteristics to aqueous and viscous solutions. From coatings, medical devices, dental resins to industrial research and development efforts, specialty monomers are involved in each step of refining, improving, enhancing, modifying and developing or discovering new ways to improve the overall quality of industrial raw materials and products.
