Procedure: The polyurethane polymer of Example 2 is prepared from a mixture of the ingredients in the amounts listed in Table 1, wherein Polyol A, Isocyanate A, and Catalyst A are as identified in Example 1. Surfactant A is an organosilane surfactant degassing agent commercially available form Union Carbide Corp. under the trade designation L-5304. Isocyanate B is a mixture of methylene diphenyldiisocyanate with tripropylene glycol and dipropylene glycol, having an average molecular weight of 364, commercially available from The Dow Chemical Company under the trade designation Isonate 181. Polyol B is a polyether triol of 2600 molecular weight formed from a heterofeed mixture of 50 weight percent ethylene oxide and 50 weight percent propylene oxide commercially available from The Dow Chemical Company under the trade designation Polyglycol 15-200. Polyol C is a 400 molecular weight polyether having about 100 weight percent oxyethylene groups and a nominal functionality of 2. The mixture is vacuum degassed for 2 minutes. Then, Isocyanate A is mixed into the mixture to form an admixture which is degassed for and additional 2 minutes. The admixture is poured into a open steel mold which is maintained at a temperature of 50° C. for a period of 8 hours, after which it is placed in an oven at 180° F. for a period of 24 hours.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a 0.5 L separable flask, 0.1 mol of tripropylene glycol and 0.1 mol of methacrylic anhydride were mixed in anhydrous tetrahydrofuran. After stirring the mixture for a while, the internal pressure of the container was reduced to volatile the content and the material was distilled off to obtain tripropylene glycol monomethacrylate. the material was distilled off

Procedure: Tripropylene glycol (57.6 g, 0.3 mole) was treated with p-nitrobenzoyl chloride (116 g, 0.625 mole), following the general procedure described in Example 1, Part A. The product, bis-(4-nitrobenzoyl)-tripropylene glycol (131 g), was obtained as a viscous yellow oil.

Conditions: temp:107.51; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Methyl 3,4-epoxycyclohexanecarboxylate (50 g), and tripropylene glycol (33.8 g) in 60 milliliters (“mL”) of heptane were heated in a flask equipped with a 120-mL insulated Vigreaux column, Dean-Stark trap, drying tube and magnetic stirrer. The Dean-Stark trap was pre-filled with heptane. After refluxing the heptane for 60 minutes to azeotropically remove any water moisture, 0.0340 g of anhydrous sodium acetate (406 ppm by weight based on undiluted starting materials) was added as a transesterification catalyst. Methanol/heptane azeotrope was collected in the Dean-Stark trap and heating was continued for 405 minutes. The reaction temperature gradually increased from 102 to 113° C. during the course of the reaction, and the lower (methanol-rich) layer had a volume of 20.2 mL. Heating was continued and a nitrogen sparge was used to help remove any remaining heptane solvent by distillation. The product was allowed to cool to room temperature. The product consisted of 86 wt % of the mono and diepoxide adducts of tripropylene glycol, 0.8 wt % residual monoepoxide, and 14 wt % higher oligomers by uncorrected size-exclusion chromatography using THF solvent and a refractive index detector. Purity by gas chromatography was 88%. The viscosity of the product was 380 centipoise (cP) and the epoxy equivalent weight (titration) was 245 (theoretical 230). The product resin was formulated into a photo-crosslinkable material without further purification. equipped with a 120-mL drying tube and magnetic stirrer The Dean-Stark trap was pre-filled with heptane After refluxing the heptane for 60 minutes to azeotropically remove any water moisture, 0.0340 g of anhydrous sodium acetate (406 ppm by weight based on undiluted starting materials) was added as a transesterification catalyst Methanol/heptane azeotrope was collected in the Dean-Stark trap heating Heating a nitrogen sparge to help remove any remaining heptane solvent by distillation to cool to room temperature The product resin was formulated into a photo-crosslinkable material without further purification
