Process for the manufacture of low gloss resins. |
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. <IMAGE> |
