Polymers in medical devices

Silly Putty experimentVinyl alcohol Monomer Tetrahydroxyborate anion Cross-Linking AgentBasic building block for polymer synthesisLinkers that chemical bond polymer chain togetherPoly(vinyl alcohol) Polymer

How does a cross-linker work?

Cross-linker affect on material propertiesMore chains linked togetherIncreasing stiffnessLess range of motion available rigid and stiffNo chains linked togetherLarger range of motion available to some chains more bouncy

**Basically, depending on the monomer you use or there combination you can achieve different type of materials that we use everyday*Think of this like a bead and the finished chain the necklace.*Addias shoe: http://www.chemicals-technology.com/projects/BASF-HPPO/BASF-HPPO2.htmlPVC : http://earth911.com/recycling/plastic/pvc/ accesssed June 21,2010Cup: http://www.slsonline.co.uk/showdetails.asp?id=2148Contact:http://hanshaupt.files.wordpress.com/2009/06/soft-contact-lens.jpgNalgene:http://reusablebags.typepad.com/photos/uncategorized/2008/01/16/nalgene_bottles.jpgCoke: http://mypatiofarm.files.wordpress.com/2009/05/coke_2litre_bottles2.jpg ****
