Abstract: Improved process for preparing esters of .alpha.-methyl-3,4-dihydroxyphenylalanine having pharmaceutical activity via novel N-(tert-butoxycarbonyl) intermediates.

Abstract: Filled thermoplastic resin compositions are provided wherein the filler component is compatible with and does not deleteriously affect the physical properties of the resin. The filler employed is a particulate, solid sphere which can be pre-treated with a surface active agent prior to being incorporated in the resin. The resin composition can also contain other ingredients such as impact modifiers, glass fillers, and the like.

Abstract: A process is disclosed for producing copolyester-carbonates by direct polymerization of a dihydric phenol and an acid dichloride at a single pH profile level.
