Ethoxylated bisphenol

Films of 7 3 mixtures of 1-naphthyl acrylate and ethoxylated bisphenol-A dimethacrylate had better planarizing properties than any of the resins that were examined and may be useful as layers for etchback processing. For use as bottom layers in multilayer-resist structures it will be necessary to bake the films after uv hardening to increase the Tg, and if the exposure wavelength is above 300 nm, an appropriate dye must be added to eliminate substrate reflections that degrade resolution. 

The step 1 product, bisphenol A diglycidyl dimethacrylate, ethoxylated bisphenol A dimethacrylate, triethlyene glycol dimethacrylate, bisphenol A diglycidyl dimethacrylate, and diphenyl iodonium hexafluorophosphate were mixed with diphenyl iodonium hexafluorophosphate and then heated to 85 °C for 5 minutes and mixed in a DAC 150 FV speed mixer for 1 minute at 3000 rpm. Silane-treated, nano-sized silica and zirconia particle filler were then added and the mixture reheated to 185°C for 5 minutes. It was then remixed in a DAC 150 FV speed mixer an additional 1 minute at 3000 rpm and the dental composition isolated.

Propoxylates of bisphenol A with 2 mols of PO/mol of bisphenol (15.28) and of the ethoxylated bisphenol A (15.29) with 2 mols of EO/mol of bisphenol have been used for many years as aromatic diols in the synthesis of unsaturated polyesters [29]. 

Both aromatic diols are solid, at room temperature, with convenient melting points and have high aromaticity. Thus, the propoxylated bisphenol A has an aromatic content of 46.7% and ethoxylated bisphenol A an aromatic content of around 48%.

Dental resin formulations were prepared by the combination of SOCM with an ethoxylated bisphenol A dimethacrylate (EBPAD, Diacryl 101, Akzo Chemie America) in a 26.6 73.4 wt ratio which corresponds to a 41.5 58.5 mol ratio. Resin samples were activated by the addition of various photo-initiators and were polymerized as unfilled films between Mylar sheets. The cured samples were stored for 24 h at 37 C and then removed from the Mylar. The degree of conversion of the combined methacrylate groups of SOCM and EBP AD as well as the conversion of the spiro vinyl group of SOCM were determined by comparison of the IR spectra of the uncured resin with those of the polymerized films. The methacrylate double bond absorption at 1637 cm and the spiro vinyl absorption at 880 cm were monitored with the aromatic band at 1585 cm utilized as an internal standard reference 14),... 

The monomers that yielded homo- or copolymers were formulated into composites. Three comonomers, PBD, PBMD and p-dimethoxybenzene (DMOB), were combined individually with EBPADM, an ethoxylated bisphenol A dimethacrylate (Diacryl 101, Nouiy Chemicals), in various ratios to form the resin components of the composites. The initiator system used was 0.4 wt% camphorquinone (CQ) and 0.8 wt% ethyl 4-A, A -dimethylaminobenzoate (4-EDMAB).

Unsaturated polyesters are the most versatile class of thermosetting polymers. They are macromolecules made up of an unsaturated component, (i.e., maleic anhydride or its trans isomer, fumaric acid, which provides the sites for further reaction) and a saturated dibasic acid or anhydride with dihydric alcohols or oxides (typically phthalic anhydride which can be replaced by aliphatic acid, like adipic acid, for improved flexibility). If blends of phthalic anydride (or isophthalic acid) and maleic anhydride/fumaric acid are used, ortho (or iso) resins (Figure 6.18) are obtained. On the other hand, if propoxylated or ethoxylated bisphenol A is used with fumaric acid, bisphenol A fumarates are obtained, if a blend of chlorendic...
