We report the case of a manicurist who developed an allergic skin reaction to acrylates, manifested by bullous lesions on fingertips and eczema of the hands and ears. Patch tests showed positive reactions to 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, ethyleneglycol dimethacrylate, triethyleneglycol dimethacrylate, 1,6-hexandiol diacrylate, 2-hydroxyethyl acrylate and triethylene...

Thermolysis of the 3,5-hexadienyl acrylates (a) proceeds via the transition state E in which the connecting chain adopts a boatlike conformation due to a preference for maintaining ester overlap to afford the products b with good diastereoselectivity.

the development of efficient and safe carrier system to transfer dna into cells is essential in non-viral gene therapy. the aim of the present study was to evaluate the effect of linear polyetheneimine (lpei) (2500 da) on the physicochemical and biological properties of lipopolyplexes constructed from liposomes and lpei. materials and methods different lipopolymers were synthesized from lpei an...

[Structure: see text] The enantioselective hydrogenation of beta-phthalimide acrylates provides the corresponding chiral beta2-amino acids in excellent enantiomeric excess catalyzed by Rh-monophosphorus.

A multitude of acrylic monomers is used in dentistry, and when dental personnel, patients or students of dental medicine become sensitized, it is of great importance to identify the dental acrylic preparations to which the sensitized individual can be exposed. Numerous studies confirm high incidence of sensitization to (meth) acrylates in dentatal professionals, as well as in patients undergoin...

BACKGROUND Acrylates are used in a wide variety of products such as solvents, adhesives, paints, printing ink, soft contact lenses, porcelain nails, and methacrylates (used by dentists and orthopedists). Currently there are various types of acrylic compounds: acrylates, cyanoacrylates (such as tissue adhesives and home glues), and methacrylates (prostheses and dental and orthopedic fillings). T...

A temperature-driven anchoring transition in a polymer/nematic fluid composite that is far from the bulk nematic-isotropic transition temperature is reported. A series of poly(methylheptyl acrylates) were studied to probe the subtle effects of the side chain structure of the polymer on control of the anchoring. A polymer-dispersed liquid crystal film made from TL205 and 1-methylheptyl acrylate ...

BACKGROUND Allergic contact dermatitis (ACD) caused by (meth)acrylates is traditionally an occupational disease among dentists, printers, and fibreglass workers. With the use of artificial nails, cases have been reported both in nail technicians and in users. OBJECTIVES The aims of this study were to characterize ACD caused by (meth)acrylates, identify the responsible allergens, and assess th...

7-Hydroxycoumarine undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding alkyl (E)-3-((2-oxo-2H-chromen- 7-yl)oxy)acrylate in good yields. When the reaction was performed by 3-hydroxyquinoline similar alkyl acrylates were obtained.
