  • Blocky chlorinated polyolefins, process for making and use as impact modifier compatibilizer for PVC or CPVC
    Patent number: 6204334
    Abstract: Blocky chlorinated polyolefins are disclosed as compatibilizers of PVC and/or CPVC resins with polyolefin elastomers. The blocky chlorinated polyolefins facilitate the dispersion of the elastomers as a dispersed phase with the proper size for impact modification of the PVC and/or CPVC. The blocky chlorinated polyolefin provides better adhesion between the elastomer and the PVC and/or CPVC providing better physical properties such as impact strength as measured by Notched Izod and variable height impact testing (VHIT) than did the randomly chlorinated polyolefins, often used as processing aids and as impact modifiers in PVC or CPVC. The differences in properties achieved with blocky chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible (and/or co-crystalizable) with either the polyolefin elastomer or the PVC/CPVC resulting in better adhesion between phases.
