concentrate was prepared as in example 1 with this material being mixed with the same main nylon copolymer homopolymer system as was utilized in the preparation of the product as set forth in example 1 in this material however the system included 10 by weight of the substituted triazine coumarin monomer component along with the main copolymer homopolymer system as set forth in example 1 a finished product was obtained having a tensile strength of approximately 105 000 psi a substituted triazine coumarin and nylon polymer mixture was prepared utilizing the substituted triazine coumarin material as set forth in example 1 with the nylon constituent being the following the initial reactant mixture included 10 by weight of the triazine coumarin material balance nylon the initial material after blending was plced in a closed vessel with 8 by weight of water added the material blanketed with a continuous nitrogen flow and heated steadily to a temperature of about 280 u00b0 c over a period of 4 hours the reactants were maintained at this temperature for a period of 4 hours at which time the reaction was complete this material was then blended with nylon 6 homopolymer in a ratio of 5 of the masterbatch balance nylon 6 homopolymer an extruded monofilament line was obtained having an oriented diameter of 12 mils with the material having a tensile strength of about 95 000 psi this mixture is blended.
