Abstract: A process for producing a thermoplastic material including the steps of molecularly orienting a thermoplastic material, grinding the oriented material to a particle size between about 0.01 to 10 mm and fusing the ground particulate material to substantially mutually adhere the particles thereby producing a sintered thermoplastic material. The fused product includes discrete fused particles of one or more anisotropically oriented thermoplastic polymers and exhibits isotropic increases in flexural modulus.

Abstract: The use of a specified molecular weight range of poly(alkylene ether)s, such as poly(ethylene glycol) (PEG), poly(tetramethylene glycol) (PTMG), and poly(propylene glycol) (PPG), and end-capped poly(alkylene ether)s, as plasticizers for polyesters such as poly(ethylene terephthalate) (PET), poly(propylene terephthalate) (PPT), poly(butylene terephthalate) (PBT), poly(ethylene naphthalate) (PEN), and poly(1,4-cyclohexanedimethylene terephthalate) (PCT), that are non-volatile during drying processes as well as during melt processing. Such poly(alkylene ether)s and end-capped poly(alkylene ether)s decrease the melt viscosity of the polymer matrix and depress the glass transition temperature, and thereby improve the processability of polyesters.

Abstract: The use of an amorphous polymer blended with a semicrystalline polymer to render the latter susceptible to adhesion promotion for good peel strength after electroless copper plating, while maintaining the advantages of the semicrystalline polymer including high temperature characteristics, ease of molding, and low cost is disclosed. The invention provides an injection-moldable material with the advantages of a semicrystalline thermoplastic but that can be made to accept electroless metal deposits for fabrication of electronic devices. The material is a blend including a high-temperature semicrystalline thermoplasstic polymer with an amorphous polymer that is easily etched and that is preferably compatible with the semicrystalline polymer. A preferred exemplary blend comprises poly(cyclohexylenedimethylene terephthalate) with polyethersulfone and/or polyarylate.
