The high oil absorption resin can clean up the oil spill which has been noted as a major cause for environment pollution．But the crosslinking network of the high oil absorption resin by chemical crosslinking agent is so tight that there are two problems for the resin to absorb oil

low oil absorbency and low releasing for oil-absorbed resin．The low oil absorbency will cause more resin to be used．The oil absorbed resin which can not be cyclically used will cause a solid pollution again．In order to solve these two problems

the concept of physical crosslinking is introduced into the research field of oil absorption resin which is traditionally crosslinked chemically only to loose the chemical crosslinking network．Acrylic-based high oil absorption resins with both chemical crosslinking and physical crosslinking were prepared in the suspension polymerization．The oil absorption rate and optimized ratio of two monomers in two kinds of different resins are compared．The oil absorption properties of two kinds of different resins produced from monomer with low affinity to oil and effects of the quantity of chemical crosslinking agent on them are compared too. Results indicate that the introduction of physical crosslinking will improve the oil absorption properties

including raising oil absorption rate and increasing oil absorbency of resins produced from monomer with low affinity to oil. In addition

it increases the quantity of monomer with low affinity to oil in optimized ratio of monomer．Results also indicate that partially physical crosslinking resin have a best amount range of chemical crosslinking agent．
