Definitions
- This invention is directed to a curable
- the reaction product In the uncured state, the reaction product has a lower f viscosity than the corresponding unmodified resin.
- the increased cross-linking density provides improved heat distortion temperatures and hardness and a decrease in water and solvent sorption.
- the vinyl ester resins useful in making the reaction product must have more than one secondary hydroxyl group in the polymer chain.
- the vinyl ester resin can be prepared from any glycidyl polyether.
- Useful glycidyl ethers are those of polyhydric alcohols and phenols. Such glycidyl polyethers are commercially available or are readily prepared by reacting at least two moles of an epihalohydrin or glycerol dihalohydrin with one mole of the polyhydric alcohol or phenol together with a sufficient amount of caustic to react with the halogen of the halohydrin. The products are characterized by the presence of more than one glycidyl ether group per molecule.
- the useful acids for making the vinyl ester resins are those ethylenically unsaturated monocar- boxylic acids such as acrylic, methacrylic, cinnamic acids and their halogenated isomers. Also included are the hydroxyalkyl acrylate or methacrylate half esters of dicarboxylic acids as described in U.S. Patent No. 3,367,992 wherein the hydroxyalkyl group preferably contains from 2 to 6 carbon atoms.
- the glycidyl ether and the acid are reacted in about stoichiometric equivalency generally with 5 heating in the presence of a catalyst, such as a tri- valent chromium salt, as, for example, chromium tri ⁇ chloride or a tertiary amine, as, for example, tris- (N,N-dimethylaminomethyl phenol).
- a catalyst such as a tri- valent chromium salt, as, for example, chromium tri ⁇ chloride or a tertiary amine, as, for example, tris- (N,N-dimethylaminomethyl phenol).
- Vinyl polymerization inhibitors are also commonly included to prevent pre- 10 mature polymerization.
- a reactive diluent usually a copolymerizable monomer.
- Suitable monomers for this use include vinyl 15 aromatic monomers, such as styrene and vinyltoluene, and acrylate or methacrylate esters of lower alkanols.
- the reactive diluent may be an amount of up to 60 weight percent of the combined resin/monomer weight.
- the isocyanatoethyl methacrylate is employed 20 in an amount of 0.05 to 1.00 equivalent per equivalent of hydroxyl. Less than about 0.05 equivalent imparts little observable change in the cured product. Any isocyanate in excess of 1.0 equivalent has no place to react and thus could detract from the desired proper- 25 ties of the cured product.
- the polymer or polymer precur ⁇ sor, the reactive diluent and a catalyst, such as 30 stannous octoate, are thoroughly mixed together and
- the potential for cross-linking in the iso- cyanato product can be adjusted in several ways.
- the amount of unsaturation in the polymer or precursor can be varied.
- the number of hydroxyls in that starting material can vary.
- the amount of unsaturated isocyanate can be adjusted to that providing the desired number of cross-links. Some of the hydroxyls can be reacted with a saturated aliphatic isocyanate.
- the products have improved, properties, par- ticularly heat distortion temperature, hardness and low solvent sorption.
- the products find use as neat resins and in reinforced plastics. Of particular note are their use in fiberglass reinforced filament wound pipe, electrical laminates, electrical insulating varnishes and coatings, bulk and sheet molding compounds, and corrosion resistant vessels and linings for vessels.
- trimethacrylate of tris(4-glycidylphenyl)methane 25 parts of styrene and 0.1 part stannous octoate were mixed while heated to 50°C. To that mix while stirred was slowly added 47.02
- IEM isocyanatoethyl methacrylate
- trimethacrylate with 20 percent styrene was cured in an identical manner.
- the samples were tested according to standard methods with the following results.
- the heat distortion temperature of the nonmodified resin was 203°C and of the IEM modified resin was greater than 230°C.
- the Barcol Hardness of the former was 42 and of the latter was 50.
- a resin was prepared according to the pro ⁇ cedure and stoichiometry of Example 1 using the di eth- acrylate of the diglycidyl ether of bisphenol A as the polymer and vinyltoluene as the reactive diluent.
- the resin was cured with 1.5 parts benzoyl peroxide per 100 parts of resin for one-half hour at 150°C.
- the samples were tested according to standard procedures with the following results.
