Applicant's summary and conclusion

Conclusions:
LCCPs are present in two different forms at room temperature/pressure based on the chlorine content of the LCCP. LCCPs with chlorination levels of 30-60% by weight are liquid. LCCPs with chlorination levels of 70-75% by weight are solid.
Executive summary:

LCCPs are present in two different forms at room temperature/pressure based on the chlorine content of the LCCP. LCCPs with chlorination levels of 30-60% by weight are liquid. LCCPs with chlorination levels of 70-75% by weight are solid.
