摘　　要：A kind of PEG-MAH（maleic anhydride to modify polyethylene glycol） crystalline polymer whose melting point was approximately 64 ℃ was synthesized, and its thickening traits to LPMC were also investigated. The analysis of rheological properties indicates that the dosage and adding methods of crystalline polymer have a direct effect on the viscosity of LPMC, and that the thickening method of using melting dispersal and freezing is propitious to the thickening process of SMC. Additionally, it is also shown that SMC＇ s viscosity decreases along with the elevation of temperature, and that it reduces rapidly at the medium range of temperature, which is propitious to the dispersal of SMC in mould, and to its low pressure molding as well.A kind of PEG-MAH（maleic anhydride to modify polyethylene glycol） crystalline polymer whose melting point was approximately 64 ℃ was synthesized, and its thickening traits to LPMC were also investigated.
