A low organic emission composition comprising a di-alkoxylated bisphenol-A dimaleate urethane dimethacrylate hybrid resin, an alkoxylated bisphenol-A diacrylate or dimethacrylate, ethylene glycol dimethacrylate and other vinyl monomers. The composition is useful in such applications as a substitute for prior art resins, such as polyester/vinyl ester based resins, typically used in fiberglass reinforced plastic applications.

Bisphenol-A based polymers having low organic emissions

The present invention relates to a composition comprising at least one alkoxylated bisphenol-A diacrylate or dimethacrylate, ethylene glycol dimethacrylate, and at least one vinyl monomer. The composition is suitable for use in the fiberglass reinforced plastic art. The composition possesses similar or superior physical properties compared to unsaturated polyester based specialty resins, including emitting lower levels of organic volatiles than typical resins used in the art.

Low organic emission resins

A laminating resin is made from (1) an unsaturated polyester resin comprising maleic acid, phthalic acid, and glycol(s), (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) ethylene glycol dimethacrylate. The resin requires no styrene to achieve excellent laminating resin properties, and is significantly inhibited from emitting volatiles during use.

Laminating resins having low organic emissions (II)

A laminating resin is made from (1) an unsaturated polyester resin, (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) styrene, divinyl benzene or a combination thereof. The resin achieves excellent laminating resin properties, and is significantly inhibited from emitting volatiles during use.

Laminating resins having low organic emission (III)

A laminating resin is made from (1) an unsaturated polyester resin, (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) vinyl toluene. The resin requires no styrene to achieve excellent laminating resin properties, and is significantly inhibited from emitting volatiles during use.

Laminating resins having low organic emissions (I)

A method of laminating a solid formed body utilizing a laminating resin characterized by low volatile emissions is made from (1) an unsaturated polyester resin comprising maleic acid, phthalic acid, glycol(s), and dicyclopentadiene, (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) a compound selected from the group consisting of ethylene glycol dimethacrylate, vinyl toluene, styrene, and divinyl benzene.

Laminating resins having low organic emissions

A liquid phase esterification process is described wherein the esterification catalyst is a titanium zeolite.

Esterification process using a titamium zeolite catalyst

A process for the titanate catalyzed preparation of plasticizers from polycarboxylic acids and alcohols which minimizes waste water and is energy efficient. The reaction product is treated with aqueous caustic and is then filtered using an absorbent medium which removes titanium, caustic, acid salts and water. The need for water washing is obviated, and the final plasticizer product has excellent properties.

Method of making plasticizers

A laminating resin is made from (1) an unsaturated polyester resin comprising maleic acid, phthalic acid, and glycol(s), and dicyclopentadiene, (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) EG dimethacrylate. The resin requires no styrene or other monomer, although up to 20% vinyl toluene or 40% cyclohexyl methacrylate may be used to adjust viscosity.

A laminating resin comprising (A) an acrylated or methacrylated cycloaliphatic epoxide, (B) an acrylated or methacrylated alkoxylated bisphenol-A, in a weight ratio of (A) to (B) of about 3 to 1 to about 1 to 5, and (C) about 5% to about 50%, based on the total composition, cyclohexyl methacrylate. Vinyl toluene and ethylene glycol dimethacrylate are also used to modify certain properties of the resin.
