Heat-Resisting Expandable Microspheres Utilizing Interactions between Methacrylic Acid and Metallic Salts

Preparation of silver-poly(acrylamide-co-methacrylic acid) composite microspheres with patterned surface structures

Acrylamide (AM) and methacrylic acid (MAA) copolymer microgels were prepared by a reverse suspension polymerization technique. The microgels were used as templates for the preparation of silver-poly(acrylamide-co-methacrylic acid) [Ag-P(AM-co-MAA)] composite microspheres. The surface structures of the microspheres prepared in this way are characterized by zigzag-like structures. It was found th...

Metallic Salts of Ammono Acids.

The Action of Liquid-Ammonia Solutions of Ammono Acids on Metallic Amides, Imides, and Nitrides. The acid amides and imides, and the metallic derivatives of the acid amides and imides are the acds, bases, and salts respectively of an ammonia system of acids, bases, and salts.1 Guided by the relationships implied in the above statement Franklin and Stafford were able to prepare potassium derivat...

Balloon-expandable Metallic Stents for Airway Diseases.

Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metalli...

Acrylic acid and methacrylic acid based hydrogels-A review

Hydrogels are three-dimensional polymeric networks those swell quickly by imbibing a large amount of water or deswell in response to even miniscule changes in their external environment. The water uptake or swelling may be thousands of times of their initial volume in water. The volume phase transitions as a response to different stimuli make these materials interesting objects of scientific ob...
