  • Patent number: 6277915
    Abstract: Block chlorinated polyolefins are disclosed as performance enhancer of high rubber graft copolymers or chlorinated polyethylenes impact modifier in PVC and/or CPVC resins. The block chlorinated polyolefins (e.g. block chlorinated polyethylene) provide good dispersion of the impact modifier particles in the matrix and better adhesion between the impact modifier and the PVC and/or CPVC interface, providing better physical properties such as impact strength as measured by Notched Izod 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 block chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible with either the impact modifier or the PVC/CPVC resulting in better adhesion between phases.
