Learn about polyacrylic acid. Understand the definition of polyacrylic and acrylic acid, also explore examples of acrylic acid polymer and...
PURPOSE: To obtain a W/O natural or synthetic oil emulsion lowly irritating to the skin by using a polyacrylic acid long-chain alkyl ester synthesized from specified starting materials and having a low content of a low-molecular weight component and a narrow molecular weight distribution width as...
Acrylic acid (AA), dehydrated ethanol, sodium hydroxide (NaOH), potassium persulfate (KPS) and N,N,N’,N’-Tetramethylethylenediamine (TMEDA) were purchased from Sinopharm Chemical Reagent Co., Ltd. All above chemicals and regents used were analytical grade without further purification. Isolation ...
Synthetic materials that are implanted in the body become coated immediately with a layer of proteins [1] either from the adjacent tissue or from blood in the surgical field. This protein layer can stimulate the foreign body response (FBR) leading ultimately to “rejection” of the implant by ...
The calcium carbonate may be present in natural form as limestone, chalk or marble or in a synthetic form as precipitated calcium carbonate. The milling is carried out continuously or batchwise in aqueous suspension. The calcium carbonate content in this suspension is as a rule ≧50, preferably...
Microbial communities are more effective in degrading natural polymers and xenobiotics than pure cultures. Biodegradation of polyacrylic and polyurethane polymers by bacterial and fungal strains has been addressed, but limited information about their biodegradation by microbial communities exists. The aim of...
Its chemical nature may be organic, of synthetic origin, and it may consist of any plastic that can be spun, for example polyolefins, polyesters, polyamides, polyvinyls, acrylics, it may be organic, of natural origin such as flax or cotton, or it may be inorganic, for example made of ...
Novel polyacrylic acid resins are prepared by polymerizing a monomer selected from the group consisting of H2 C CHCO2 X, H2 C CR1 CO2 X, HR2
Synthetic oils for W / O- emulsifiers natural or made of the compounds and the preparation of polyacrylic acid ester having a polyoxyalkylene group and a long-chain hydrocarbon groupsPolyacrylate esters with long-chain hydrocarbon and polyoxyalkylene groups are disclosed, which are prepared by ...
