    摘要： A process for making reduced gloss thermoplastic resin compositions is provided. The process involves compounding a nitrile polymer with an electrophilic reagent to form a polymeric gel compound, blending the polymeric gel compound with a first thermoplastic resin and a weight ratio of between 5:1 and 0.5:1 to make a concentrate comprising gels dispersed in the first thermoplastic resin, and admixing the concentrate with a second thermoplastic resin produced the desired composition, wherein the concentrate is used at a level of from 2 to 60 percent by weight based on the total weight of the composition. The process provides improved product consistency, and consistently yields a product exhibiting reduced gloss and high levels of impact strength with a uniformly dispersed concentration of polymeric gels therein. The compositions are useful in making molded articles exhibiting consistent reduced gloss and high impact strengths.

    摘要： A medical device for physical therapy treatment to enable patients confined to a bed to increase upper and lower extremity strength and promote a quicker return to standing and walking activities. The medical device can be a generally wedge-shaped article constructed of a resiliently compressible material designed to consistently return to its original shape after repeatedly being compressed. The medical device can have an expansive front support base, an expansive, taller rear support base, a generally flat bottom surface, left and right sides and a top surface which slopes from the expansive front support base to the taller rear support base at an angle designed to provide a proper range of motion for a patient's legs when performing a certain therapeutic exercise. The left and right sides can be provided with opposing indentations therein at about the mid portion of the medical device. For stability while performing exercises, the front and rear support bases preferable have expansive surfaces which can be placed between a patient's feet and the footboard of a bed to permit the article to be compressed between the patient's feet and the footboard in order to perform therapeutic exercises. The left and right sides can be compressed either between the patient's thighs or between the outside of the patient's thigh and the side rail of a bed to perform therapeutic exercises. The indentations can be positioned along the sides of the article to provide an anatomically comfortable fit for the patient's thigh and knee.
