    • The present invention discloses a thermosetting resin composition including: a bi-functional or multi-functional epoxy resin, a SMA uses as a curing agent, an allyl phenol such as diallyl bisphenol A used as a co-curing agent and a toughening agent a low-bromine or high-bromine BPA epoxy resin or tetrabromobispheno A (TBBPA or TBBA) uses as a flame retardant agent, and an appropriate solvent. After the resin composition of the invention is cured, the resin composition has lower dielectric property and better thermal reliability and tenacity. A copper clad laminate made of an enhanced material such as glass fiber has lower dielectric constant (Dk) and loss tangent (Df), high Tg, high thermal decomposition temperature (Td), better tenacity and PCB manufacturability, and thus very suitable to be used as a copper clad laminate and a prepreg for manufacturing PCBs or applied as a molding resin material for contraction, automobile and air navigation.

    • Triclosan, a diphenyl ether additive characterized by molecular electrochemical functionality, is proposed as a unique compatibilizer with nonpolar bisphenyl vinyl ester thermosets and especially those resins containing hydroxyl groups. Electrochemical functionality is being described as alternating conformational changes related to molecular asymmetry where a dipole is either hidden alongside the ether dihedral angle with phenyl planes at about 30 degrees, or the dipole becomes exposed as the phenyl planes rotate toward 90 degrees. Accentuated electrochemical compatibilization through nonbonded Lennard-Jones parameters with molecular similarities related to closer intermolecular distances involves resin polymer chain and monomer entanglement for increased toughness and other improved mechanical properties. Triclosan compatibilization with bisphenyl-A vinyl esters is extreme, allowing major concentrations to be incorporated. The dipole of Triclosan is particularly important where it can open up in the presence of more polar elements or functional groups such that extra curing agents may be required for sufficient free radicals to ensure complete polymerization. Nonpolar electrochemical Triclosan compatibilization is further related to hydrophobic wetting viscosity reduction with disruption of secondary bonding. Lowered resin viscosity then promotes entropic mixing stabilization to improve homogeneous dispersion during fiber resin impregnation with vinyl esters and related monomers, for inclusion of filler particulate, or other polymer modifiers. Hydrophobic wetting becomes especially important when incorporating high levels of filler into molding compound where resin mobility is significantly restricted by reinforcing fibers necessary for mechanical strengths. Additionally, hydrophobic wetting reduces interfacial porosity to improve composite mechanical and physical properties.
