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 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.

Silyl derivatives of 2,6 dimethyl, 4-allyl phenol include compositions of the formula ##STR1## where R.sup.1, R.sup.2, and R.sup.3 are independently selected from alkyl and phenyl groups having up to about eight carbon atoms and/or are connected to form one or more rings. They may be made by silylating the corresponding hydroxyl compound. They are useful as comonomers for olefins to introduce functional sites in high molecular weight copolymers.

Silyl derivatives of 2,6-dimethyl-4-allyl phenol

Thermosetting compositions comprise, (a) about 10% to about 60% of a polymerizable olefinic monomer such as styrene or vinyl toluene (b) from about 1 to about 40% of a maleimide of the formula: ##STR1## where R.sup.1 and R.sup.2 are independently selected from hydrogen or C.sub.1-3 alkyl groups, and in which the phenyl group may be substituted with aliphatic, alicyclic, and aromatic groups and up to three halogen or hydroxyl groups, and (c) about 5% to about 89% unsaturated polyester. The compositions are useful for their electrical and heat resistant properties as molding compositions, for the impregnation of electrical coils and for encasing electrical components.
