Aromatic polymers of rubber modified high gloss produced by a process of bulk polymerization movilinilideno.

摘要

A polymer composition modified mass polymerized rubber comprising: a continuous matrix phase comprising a polymer of a monovinylidene aromatic monomer and optionally a monomer ethylenically unsaturated nitrile, and discrete rubber particles dispersed in said matrix, produced said particles rubber from a rubber component comprising from 5 to 100 weight percent of a functionalized diene rubber having at least one functional group per rubber molecule capable of enabling controlled radical polymerization; wherein the composition is further characterized by: a) an average size of rubber particle volume from about 0.15 to 0.35 micron, b) a total rubber phase volume between 12 and 45 percent, based on the volume total combination of the matrix phase and the rubber particles; c) a partial rubber phase volume between 2 and 20 percent characterized by rubber particles having an average particle size greater than 0.40 micrometers by volume; and d) a crosslinked rubber fraction of at least 85 weight percent, based on the total weight of the rubber particles; It is the ad parameters measured by the methods described in the description.
