1) Olefin polymerizations


In our laboratory, more than 100 new titanium and zirconium complexes have been preapred for olefin polymerizations for the last two decades. Especailly, organolithium compounds have been actively utilized in the construction of those complexes. The representative complexes1 and 2 can be prepared in two steps in Kg-scale, which exhibit high activity, high 1-octene incorporation, and high molecular weight in the ethylene/1-octene copolymerizations. Complex 1 is currently used in industry (LG) for the production of polyolefin elastomers (~80,000 T/y) and eventually complex 2was licensed out to Lotte Chem in 2011 with affront fee 600,000,000 Won.

2) CO2/epoxide copolymerization


A highly active catalyst (3) was discovered for the CO2/epoxide copolymerization. Complex 3 showed a high TON up to ~20000 and a high turnover frequency (TOF) of ~20000 h-1 that produced a strictly alternating copolymer with a high molecular weight (Mn) of up to 300000. The catalyst was licensed out to SK in 2008 with affront fee 600,000,000 Won.


3) New compostable polymers from CO2


High-molecular-weight poly(1,4-butylene carbonate-co-terephthalate)s were prepared by condensation copolymerizations of 1,4-butanediol, dimethyl carbonate, and dimethyl terephthalate, which shows the comparable thermal properties to the commercialized compostable polyesters such as PLA, PHA, PBAT, and PBSA. The polymers were licensed out to Lotte Chem in 2014 with affront fee 500,000,000 Won.
