A method for making a fiber-reinforced thermoplastic polymer composition and forming a fabricated article therefrom. A thermoplastic polymer, a masterbatch comprising an elastomer and a reinforcing fiber material are compounded, extruded and immediately formed into a fabricated article. The fabricated article is formed by compression molding, vacuum forming, thermoforming, injection molding, blow molding, profile extrusion or combinations thereof.

Articles comprising a fiber-reinforced thermoplastic polymer composition

Material is supplied to a mold by direct application of gas pressure to a liquid material. A method for the shaping of at least two different synthetic resinous materials by providing a predetermined quantity of up to about 100 cm.sup.3 of a first material in a first material reservoir and a second material in a second material reservoir, the first and second material reservoirs each being in communication with a discharge line having a sufficiently narrow inner diameter such that each reactive quantity may, when propelled by sufficient gas pressure, be propelled in plug flow and each discharge line being in communication with a mold; introducing into each of the first and second gas reservoirs a predetermined volume of a gas at predetermined gas pressures sufficient to propel each quantity of material as turbulently flowing plug into the mold.

Method for small scale forming of hardenable materials of organic origin

Reaction injection moldings (RIM) having increased heat resistance are provided by substituting a thiapolycyclic polyisocyanate such as dimethyl-9-thiabicyclononane diisocyanate for the aromatic polyisocyanate in an otherwise conventional RIM composition.

Reaction injection molded polyurethanes, polyureas and

Reaction injection moldings (RIM) having increased heat resistance are provided by employing a thiapolycyclic polyahl such as dimethyl-9-thiabicyclononane diamine as a chain extender in an otherwise conventional RIM formulation.
