Latest Patents
One of Handa's latest patents focuses on compositions for paints and printing inks. This invention involves block copolymers of a vinyl-substituted aromatic hydrocarbon and a conjugated diene. These copolymers are created by polymerizing the respective monomers using an alkali metal or organo alkali metal initiator. The resulting block copolymer is then treated with a polar reactant to introduce polar groups into the polymer chain terminal. Inorganic pigments are incorporated into the block copolymer to prepare the final compositions for paints and printing inks.
Another significant patent by Handa pertains to organolithium polymerization initiators and their preparations. This invention describes a stable and non-polar solvent soluble alpha-methylstyrene-conjugated diene oligomer dilithium as a polymerization initiator. The process involves reacting lithium metal with alpha-methylstyrene in a polar solvent at low temperatures, followed by the gradual addition of a conjugated diene to create the stable oligomer.
