Abstract: | With PET wastes, through catalytic alcoholysis, esterfication and polycondensation, a new unsaturatedpolyester resin (UP) is prepared whose cost per ton is 500 yuan less than that the conventional UP resin,i which has a molecular weight of 1900~2300, acid value 19~29,and a storage life of 8 months.? 15 ? |
