The use of unsaturated polyesters and additives such as styrene reduces the viscosity of the resin. The initial liquid resin is converted to a solid by a crosslinked chain. This process is accomplished by generating free radicals at unsaturated bonds that extend in the chain reaction to other unsaturated bonds of adjacent molecules, thereby joining adjacent chains in the process.Polyurethane resin
Polyurethanes contemplated for use in the practice of the invention refer to polymers composed of chains of organic units linked by carbamate/urethane linkages. The polyurethane polymer is formed by reacting isocyanic acid with a polyol.

HALS acts by neutralizing the free radical intermediates produced by UV rays to neutralize the degradation. In both cases, the damaging effects of the UV light are directed away from the matrix polymer and the colorant due to interaction with the UV additive present in the matrix polymer. As used herein, the term "membrane toughening agent" refers to an agent that imparts flexibility to a film prepared from a formulation containing the same. As used herein, the term "phenol-novolak hardener" refers to a material that participates in further interaction of the reactive groups such that it increases its cross-linking, thereby enhancing its hardness.

EXAMPLES Example 1 Synthesis Step for Compound I An exemplary polyaromatic compound (Compound I) according to the present invention was prepared as follows.Nikanol Y-100 (100.0 g, 0.04464 mol) from Fudow Co. Ltd. and 100 ml of toluene were added to a three-necked round bottom flask equipped with a magnetic stirrer. The resulting mixture was cooled to 0-10 ° C using an ice bath. To this mixture was added 4.041 g (0.04464 mol) of trimethylamine. Propylene hydrazine chloride (5.01 g, 0.0494 mol) was then introduced dropwise into the mixture via an addition funnel. The rate of addition was controlled such that the temperature of the reaction mixture was always kept below 10 °C. After all the ingredients were introduced, the mixture was naturally allowed to warm to room temperature and the reaction was allowed to proceed for another 6 hours. The reaction mixture was then washed twice with a baking soda aqueous solution, followed by washing twice with distilled water. The organic layer was dried over magnesium sulfate and filtered through a filter paper. The toluene solvent was then removed by vacuum to give a colorless, low-viscosity liquid, 94.2 g. This resin exhibited an RI value of 1.56 at 589 nm. Example 2 Synthesis Step for Compound II An exemplary polyaromatic compound (Compound II) according to the present invention was prepared as follows. Nikanol Y-50 (100.0 g), toluene 100 ml, trimethylamine 4.041 g, and metharyloyl chloride 5.12 g were placed in a three-necked round bottom flask in a synthetic procedure similar to that described above. The reaction product was a colorless, low viscosity liquid of 89.6 g. This resin exhibited an RI value of 1.56 at 589 nm.
