Starch is a renewable natural polymer that can be decomposed easily in the environment and can be modified to various applications such as biomedical, agricultural and pharmaceutical applications. Copolymerization of gelatinized starch–CM-chitosan and acr... see more

Ethylene/1-hexene copolymerization was performed over titania-supported zirconocene/dMMAO catalysts. Effects of titania having different phases on the catalytic activity and polymer properties were investigated. It was found that anatase titania exhibited... see more

A series of titanium complexes bearing ansa-(fluorenyl)(amido) ligands with cyclohexylamido, isopropylamido, and isobutylamido groups were synthesized and their catalytic behaviors for the copolymerization of ethylene with isobutylene were compared with t... see more

Different mesoporous titanias synthesized by hydrolysis and polycondensation reactions of tetrabutyl titanate with various hydrolysis ratios (H2O/Ti by mole) were employed as supports for zirconocene/MAO catalysts in ethylene/1-olefin copolymerization. Th... see more

With zinc glutarate loaded molecular sieve catalyst in supercritical CO2, the copolymerization of CO2, propylene oxide, and maleic anhydride was studied in detail. The optimum conditions of copolymerization are: T = 70?, P = 8MPa, reaction time 15 hours, ... see more

Porous organic polymers (POPs) have received much attention in adsorption, separation, and catalysis. In this paper, porous organic polymers with different pore structure were used as metallocene catalyst supports, and ethylene/1-hexene copolymerizations ... see more

In this study, high density polyethylene (PE) film (thickness 80 µm) was modified by grafting of acrylic acid (AA) onto the film using 15 kGy of g irradiation as initiator, applied at different exposure times. In addition to irradiation dose, other variab... see more

Cassava waste pulp (CWP) contains high carbohydrates that can be modified into super absorbent polymer (SAP) through grafting and cross-linking copolymerization. Acrylamide (AM) was grafted onto CWP with ammonium persulfate (APS) as the initiator and N,N'... see more

Chemical modification of natural rubber latex by emulsion graft copolymerization with thermoplastic monomer produces thermoplastic natural rubber (TPNR). Ratio composition of natural rubber to thermoplastic monomer determines the TPNR properties. TPNR has... see more
