A porous polymer composition including plural linear mixed polarity polymer particles, wherein the particles include a linear poly[(non-polar olefin)-(polar olefin)] and at least one pore, is disclosed, as are those particles further including a catalytic component. A method of forming the plural linear mixed polarity polymer particles is also disclosed. A method of using plural linear mixed polarity polymer particles which include a catalytic component to catalyze polymerization is further disclosed. A porous polymer composition including plural linear non-polar polymer particles and a catalytic component is further disclosed, along with a method of making those linear non-polar polymer particles including the catalytic component and a method of using them to catalyze polymerization.

A polymerizable composition including a late transition metal complex, a non-polar olefin, a polar olefin, and a free radical scavenger, wherein the polymerizable composition is capable of forming a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer, is disclosed. A method of copolymerizing a non-polar olefin with a polar olefin, catalyzed by a late transition metal complex in the presence of a free radical scavenger, to produce a linear poly[(non-polar olefin)-(polar olefin)] substantially free of free radical addition polymer is also disclosed.

The present invention relates to a method for producing a copolymer of ethylene and a polar group-containing olefin using as a catalyst a metal complex of group 10 elements having a structure represented by formula (C4) and (C5)
(in the formula, “Men” represents a menthyl group and “Me” represents a methyl group). The method of the present invention makes it possible to produce a polar group-containing olefin polymer available for various applications, as being a high molecular weight body, which has been difficult to produce, and to produce the polymer in a molecular weight range such that the polymer has good moldability.

chiral ligands and catalysts. Despite their utility few simple catalytic methods are available for their synthesis in high enantiopurity. Herein the atropselective acylation of a range of symmetric biaryl diols is investigated using isothiourea catalysis. Studies on a model biaryl diol substrate shows that the high product er observed in the process is a result of two successive enantioselective reactions
