摘要： Recent progress in photoinitiated ring-opening metathesis polymerization (photo-ROMP) has enabled the lithographic production of patterned films from olefinic resins. The use of a latent ruthenium catalyst (e.g., HeatMet) in combination with a photosensitizer (e.g., 2-isopropylthioxanthone) to rapidly photopolymerize metathesis-monomers (e.g., dicyclopentadiene (DCPD)) upon irradiation with UV light has previously been demonstrated. See U.S. application Ser. No. 17/677,558. In addition to the exemplary catalysts and photosensitizers described in that work, a variety of alternative catalysts and photosensitizers are commercially available that allows for tuning of thermomechanical properties, potlifes, activation rates, and irradiation wavelengths. As an example, fourteen catalysts and eight photosensitizers were surveyed for the photo-ROMP of DCPD and the structure-activity relationships of the catalysts examined. Properties relevant to photopolymerization-based additive manufacturing—potlifes, printing irradiation dose, conversion—were characterized to develop catalyst and photosensitizer libraries. Two optimized catalyst/photosensitizer systems were demonstrated in the rapid stereolithographic printing of complex, multidimensional pDCPD structures with microscale features under ambient conditions.

摘要： A methodology is described for the synthesis of polyolefin containing block-copolymers using a catalytic postpolymerization modification strategy. Common polyolefin grades may be converted into macroinitiators using a cross-metathesis reaction. The functionalized polyolefins may then be used to initiate living: coordinative ring opening polymerization of cyclic ester monomer, anionic ring opening polymerization of epoxide monomer, and radical polymerization of vinylic monomer, to yield the corresponding block copolymers.

摘要： Disclosed is a new polyolefin catalyst and preparation therefor. Specifically, disclosed is a catalytic system comprising a new complex of iron, cobalt, nickel, palladium, and platinum. In the presence of the catalytic system, oily polyethylene can be efficiently obtained from simple olefins such as ethylene under mild conditions, highly branched oily alkane mixture is then obtained after hydrogenation. The alkane mixture can be used as a processing aid and a high-performance lubricant base oil. The present invention also provides a method for preparing the catalyst, a method for preparing the highly branched oily alkane mixture and a method for preparing functional polyolefin oil.
