| Abstract: | By co-equilibration polymerization,polydimethylsiloxane oligomers with pendant amine groups（NH2-PDMS）was synthesized from octamethylcyclote trasiloxane（D4） and N-β-aminoethyl-γ-aminopropylmethyl-dimethy-oxysilane（HC-500）,using hexamethyldisiloxane（MM） as end capping agent,CH3CH2OK as catalyst and dimethylsulfoxide（DMSO） as promoter.The influence of process condition to NH2-PDMS ammonia value was studied.The results showed that when the molar ratio of D4,HC-550 and MM was 45∶3∶2,the CH3CH2OK and DMSO dosage were 0.14% and 1.0%,the reaction temperature was 120 ℃ and the reaction time was 6 h,the ammonia value of synthetical NH2-PDMS was 1.0 mmol/g.The polyurethane adhesive modified by the NH2-PDMS had good comprehensive properties,lower water absorption rate,higher water resistence and salt tolerance. |
