The present invention relates to a method of manufacturing a heterogeneous material joined body.

A composition for injection molding includes specific amounts of a poly(phenylene ether), a first hydrogenated triblock copolymer, a second hydrogenated triblock copolymer, a polypropylene, a polybutene, an ethylene/1-octene copolymer, and a flame retardant. At least one of the first and second hydrogenated triblock copolymers has a pre-hydrogenation vinyl content of 50 to 100 mole percent, based on moles of incorporated polybutadiene. Injection molded articles prepared from the composition include cable connectors and their parts.

A copolymer having the structure (I) wherein Q.sup.1, Q.sup.2, Q.sup.3, Q.sup.4, m, and n are defined herein. The copolymer can be formed by oxidative copolymerization of 2,4,6-trimethyIresorcinoI with a monohydric phenol. Also describes are a composition comprising the copolymer and a solvent, and a composition comprising the copolymer and a thermosetting resin. ##STR00001##

A mechanical assembly for securing a first sheet to a second sheet includes a first projection having a first sidewall and a first top wall. The first sidewall extends from the first top wall at a first acute angle. The first sidewall includes a first top end and a first bottom end. A first discontinuity is defined in the first sidewall between the first top end and the first bottom end. A first base wall extends from the first bottom end. The first base wall extends generally parallel to the first top wall.

The present disclosure relates to an additive manufacturing (AM) method for making a three-dimensional (3D) object, using a part material (M) comprising at least one PEEK-PEoEK copolymer, in particular to a 3D object obtainable by Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) from this part material (M).

Provided are resin foam particles that enable shaping of a sound absorbing member having excellent sound absorption performance through a resin foam shaped product. Also provided is a laminate that includes a resin foam shaped product as a base material and with which high sound absorption performance can be obtained even when the laminate is a thin material. The resin foam particles contain a resin and have a recessed external part. A ratio .sub.0/.sub.1 of density of the resin .sub.0 and true density .sub.1 of the resin foam particles is 2 to 20, and a ratio .sub.1/.sub.2 of true density .sub.1 of the resin foam particles and bulk density .sub.2 of the resin foam particles is 1.5 to 4.0.
