Abstract

The ABS/PET and ITTR/ABS/PET alloys were prepared by melt blending method using hard-shell structure of isocyanate terminated silicone resin as compatibilizer. Moleculestructure of ITTR, PET and the alloys had been characterized by FTIR and mechanical properties such as impact strength, bending strength had also been measured. The best alloy recipe was obtained in the paper. FTIR show ITTR resin in isocyanate groups reacted to hydroxyl groups in PET; the isocyanate group disappeared, reducing the number of hydroxyl groups; ITTR between PET and ABS resin played the role of "molecular bridge". When quality ratio of the ITTR/ABS/PET alloy equals 4/30/70, the alloy modification effect for the mechanical properties is optimized. At this point the tensile strength, bending strength and impact strength of the alloy increases significantly to 59.97 MPa, 113.79 MPa and 9.61 KJ/m2 respectively, exceeding pure PET by 34.74% 36.19% and 66.84% respectively.
