Embodiment 1
[0017] Example 1 A method for preparing a core-shell particle toughened PBT / PC alloy, (1) Take 753 g of polybutadiene latex with a solid content of 59.7% and add it to the reactor, add 2.25 g of sodium pyrophosphate, and 3.15 g of glucose , 0.045g ferrous sulfate, 1500mL deionized water, cumene peroxide (CHP), their mass ratio is 753:2.25:3.15:0.045:1500:0.28, nitrogen protection, the reaction temperature is 70 oC . Add dropwise the mixture of methyl methacrylate, styrene, cumene hydroperoxide and TDDM in the weight ratio of 110:331:1.125:1.72 to the reactor, after the addition is completed, add the mixture in the weight ratio of 9:0.28 Glycidyl methacrylate and cumene hydroperoxide, reacted for 1 hour, coagulated, washed, at 60 oC Under the condition of drying for 24 hours, the core-shell particle (PB-g-MSG) copolymer was obtained. The TDDM content of the core-shell particles prepared in Example 1 is 0.38%, and the properties are listed in Table 1.

Embodiment 2
[0021] Example 2 Methyl methacrylate, styrene, cumene hydroperoxide and TDDM were added dropwise into the reactor at a weight ratio of 110:331:1.125:3.44, and the rest were the same as in Example 1.
[0022] The TDDM content of the core-shell particles prepared in Example 2 is 0.76%, and the properties are listed in Table 1.
[0023] Step (2) and step (3) are the same as in Example 1.
[0024] The prepared blend material was heated at 240 oC Injection into standard specimens for mechanical testing under conditions, and measure impact and tensile properties according to ASTM-D256 and ASTM-638 standards. The properties of the modified materials are shown in Table 2.
Embodiment 3
[0025] Example 3 Methyl methacrylate, styrene, cumene hydroperoxide and TDDM were added dropwise into the reactor at a weight ratio of 110:33:1.125:5.16, and the rest were the same as in Example 1.
[0026] The TDDM content of the core-shell particles prepared in Example 3 is 1.14%, and the properties are listed in Table 1.
[0027] Step (2) and step (3) are the same as in Example 1.
[0028] The prepared blend material was heated at 240 o Under the condition of C, it is injected into a mechanical test standard sample, and the impact and tensile properties are measured according to the ASTM-D256 and ASTM-638 standards. The properties of the modified materials are shown in Table 2.
