International Classification:

C08F 30/08

US Classification:

526279

Abstract:

The present invention provides transparent silicone hydrogels with high acrylamide monomer content and an excellent balance between moisture content. The silicone hydrogels may be obtained by polymerizing a monomer mix containing a plurality of monomers, wherein the monomer mix comprises about 30 to about 98% by weight of at least one type of silicone monomer which is, and about 1 to about 50% by weight of at least one type of non-silicone type (meth)acrylamide monomer containing two or more hydroxyl groups within a molecule; wherein the weight percents are based upon the total amount of monomer components and polymer components in the monomer mix.

US Classification:

114222

Abstract:

An article has a surface topography for resisting bioadhesion of organisms and includes a base article having a surface. A composition of the surface includes a polymer. The surface has a topography comprising a pattern defined by a plurality of spaced apart features attached to or projected into the base article. The plurality of features each have at least one microscale dimension and at least one neighboring feature having a substantially different geometry. An average feature spacing between adjacent ones of the features is between 10 μm and 100 μm in at least a portion of the surface. The surface topography can be numerically represented using at least one sinusoidal function. In one embodiment, the surface can comprise a coating layer disposed on the base article.
