These states are roughly grouped into three types depending on the degree of interaction: free water, intermediate water, and non-freezing water. Intermediate water is the middle state between free water and non-freezing water, and is water that gently interacts with polymers.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:flexible-table-block\/table -->\n<figure class=\"wp-block-flexible-table-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th style=\"width:12%\"><\/th><th style=\"width:22%\">Interaction with Polymers<\/th><th style=\"width:15%\">Freezing Point<\/th><th><\/th><\/tr><tr><th>Free Water<\/th><td>Weak<\/td><td>0\u2103<\/td><td>Freezes and melts at 0\u00b0C, just like ordinary water.<\/td><\/tr><tr><th>Intermediate Water<\/th><td>Moderate<\/td><td>&lt; 0\u00b0C<\/td><td>Gently interacts with polymer materials, and freezes and melts at temperatures under 0\u00b0C.<\/td><\/tr><tr><th>Non-freezing Water<\/th><td>Strong<\/td><td>Not detected<\/td><td>Does not freeze even at (minus) -150\u00b0C.<\/td><\/tr><\/tbody><\/table><\/figure>\n<!-- \/wp:flexible-table-block\/table -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"anc02\">Features and Properties\n<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p><strong>Has excellent biocompatibility.<\/strong><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Biocompatible Polymers<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"anc03\">Details of Functions\n<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>The in-vivo foreign substances reaction, rejection reaction, and other actions start when cells recognize foreign substances. Cells recognize the external world through proteins.<br>Intermediate water has a loose structure that enables it to remain on the surface of polymers for a long time, acting like a cushion layer that blocks contact between the surface of polymers and proteins and cells. This is why polymers with a high content of intermediate water are not considered by living organisms to be foreign substances.<br>In contrast, studies* have indicated that non-freezing water formed in polymers easily dehydrates proteins and causes protein denaturation, which is not preferable in terms of biocompatibility.<br>Nippon Shokubai\u2019s intermediate water polymers contain an abundant amount of intermediate water and little non-freezing water, which give them stable biocompatibility.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"style\":{\"typography\":{\"fontSize\":\"12px\"},\"color\":{\"text\":\"#6c7872\"}}} -->\n<p class=\"has-text-color\" style=\"color:#6c7872;font-size:12px\">* Journal of Biomaterials Science, Polymer Edition, Vol.3, p.127 (1992)<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:image {\"id\":8934,\"sizeSlug\":\"large\",\"linkDestination\":\"none\"} -->\n<figure class=\"wp-block-image size-large\"><img src=\"\/en\/wordpress\/wp-content\/uploads\/2022\/11\/img_materials10_002-1024x430.png\" alt=\"Illustration  of Functions \" class=\"wp-image-8934\"\/><\/figure>\n<!-- \/wp:image -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\" id=\"anc04\">Related Products<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>PMEA, which is currently used widely as a biocompatible material, is known to also contain intermediate water.
