It is an object of the present invention to provide a compound having a (meth)acryloyl group that is suitably used in various applications, a process for producing such compound simply and under mild conditions, and an useful photo-curable composition and aqueous photo-curable composition comprising such compound. The present invention is related to a process for producing a compound having a (meth)acryloyl group

(Meth) acryloyl group-containing compound and method for producing the same

Reactive diluent and curable resin composition

For example, a blended composition is produced first by letting a monomer composition, mainly composed of alkyl (meth)acrylate and including a compound having a plurality of polymeric groups within a molecule, contain microscopic particles, such as carbon black, having an average primary particle size in a range between 1 nm and 200 nm, and then the blended composition is polymerized. Consequently, it has become possible to produce inexpensive crosslinked elastomer having excellent physical properties, such as small creep (low creep) in compression set, tensile elongation set, etc., and excellent mechanical strength, such as tensile break strength and tensile break elongation, in a simple procedure omitting the post-crosslinking step at a high-level productivity while saving energy and time spent in the kneading step.

Crosslinked elastomer and producing process thereof

The present invention provides (meth)acryl syrup which shows excellent storage stability as a molding material, and also provides a method of manufacturing the (meth)acryl syrup in a shorter period of time compared with the conventional method, and a molding material which permits a molded article having excellent heat-resistance, solvent-resistance, weathering resistance, and water-resistance, etc., to be manufactured. The (meth)acryl syrup is manufactured, for example, by polymerizing a monomer component including (meth)acrylic ester and a vinyl monomer having a carboxyl group in a presence of a thiol compound, and subsequently processing the reaction mixture with maleic anhydride and a basic compound. The molding material includes the (meth)acryl syrup, and may also include a thickening agent, derivatives of succinic acid, a reinforcing material, etc.
