The present invention relates to a method of making polyacetal compositions and molded articles of these, which comprise at least one mineral filler that has not been previously coated before being mixed into the compositions.

Process for making thermally resistant mineral-filled polyacetal

A semiaromatic polyamide composite article comprising a first component comprising a fiber-reinforced material comprising a polyamide composition and reinforcing fibers and having a tensile modulus of at least about 16 GPa as measured by ISO method 527-2:1993 at a rate of 5 mm/min on test specimens having a thickness of 4 mm, a second component comprising a polyamide composition, and an optional tie layer therebetween. The polyamide composition of first component and/or the second component is a semiaromatic polyamide compositions. The second component is prepared by injection molding and/or injection-compression molding the semiaromatic polyamide composition onto the first component.

Semiaromatic polyamide composite article and processes for its preparation

Thermoplastic compositions which are painted (coated) have improved adhesion to the paint when these compositions comprise a hydrophilic polyether or polyester modified siloxane. These thermoplastic compositions are particularly suited for use with aqueous based paints, in uses such as automobile and appliance bodies and parts.

Paintable thermoplastic compositions

The invention relates to polyacetal compositions comprising a mixture of (i) a polyacetal resin, (ii) p-aramid particles and (III) a vinyl-terminated dimethyl siloxane polymer. These compositions are useful in preparing molded articles exhibiting a good balance between high self-lubricating properties and wear resistance, and especially useful in articles that are in motion with respect to other parts they are in contact with.

Polyacetal compositions with improved tribological properties

The present invention relates to a process for coating substrates assembled from at least one polymeric part, with visible polymeric surfaces, comprising successive steps of applying and curing at least one coating on the visible surfaces of the substrate. The polymeric parts comprise a polyamide composition comprising polyamide, novolac resin, and toughener. The polyamide compositions may further comprise mineral fillers, nucleating agents, and other additives. Articles coated according to the process herein are also disclosed.
