Abstract: A polyurethane adhesive is formulated using a modified polyurethane copolymer, a curing agent and an antistatic agent, and the modified polyurethane copolymer is grafted a polysiloxane compound to a polyurethane polymer and made by esterifying a polyol, a hydroxyl-containing polysiloxane compound, a multi-functional isocyanate compound and a fatty acid ester; since the polyurethane adhesive is not yellowish and easy to dry as well as has excellent fabricability, air bleeding performance and transparency, when attached to surfaces of an optical or electronic device, the protective film leaves no residue and protects the surface of the device keeping no flaws.

Abstract: A modified bismaleimide resin is made by modify bismaleimide with aromatic diamine that contains fluoro substituents through chain-growth polymerization; and modified bismaleimide resin is excellent in physical properties including a low dielectric constant Dk (3 GHz) less than 3.0, a dissipation factors (3 GHz) less than 0.02, a low resin water absorptivity ranging from 0.21% to 0.33% and an excellent processability, and is particularly suited for producing a copper clad laminate that is required to have dielectric constant Dk (3 GHz) less than 3.
