The present invention is directed to flame retardant multicomponent articles. The multicomponent articles include a reactive, migratory agent which is present in at least a first component of the article. The reactive migratory agent is capable of migrating from the first component of the article into a different component of the article under flame conditions to react with an element of that second component to produce a flame retardant effect. Applications include fibers, yarns, nonwovens, carpets, other fibrous materials, films, coating and composites.

Flame retardant multicomponent articles

Disclosed are fibers and films prepared from polyesters of a dicarboxylic acid, preferably terephthalic acid, and a diol selected from 1,3-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, or 1,3-propanediol. The fibers and films contain a multifunctional epoxide additive and, optionally, an antioxidant, and show an increased dry heat stability when exposed to elevated temperatures in the presence of air while preserving excellent hydrolytic stability. Also disclosed is a process for stabilizing polyester fibers by melt blending a polyester and epoxide additive and melt spinning. The fibers and films are particularly useful in applications requiring elevated temperatures.

Process for improving the toughness of PCT formulations by adding rubber impact modifiers

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.

Non-volatile plasticizers and flow aids for polyesters

This invention relates to a polyester composition comprising a blend of:

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.

Disclosed is a method of rendering polymeric materials hydrophilic by treating the material sequentially with different solvents. The method is especially useful in the preparation of polymeric substrates for etching.

Method of rendering polymeric materials hydrophilic for etching

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.
