[0114] Synthesis examples 1 and 2 of the polymer samples of the tackifier for thermoplastic polyester resins, and synthesis examples 3 and 4 of the core-shell type graft polymer samples are shown below.
Synthetic example 1
[0116] 200 parts of distilled water and 0.5 parts of sodium dioctyl sulfosuccinate were added to an 8-liter reaction vessel equipped with a stirrer and a cooler. Then, the inside of the container was replaced with nitrogen, and the temperature of the reaction container was raised to 70° C. while stirring. After adding 0.2 parts of potassium persulfate and stirring for 15 minutes, a mixture of 5 parts of GMA, 68 parts of MMA, 17 parts of BA, and 1.0 part of TDM was continuously added over 4 hours. 1 hour after the addition, 3 parts of MMA and 7 parts of BA were continuously added within 1 hour, stirred for another 1 hour after the addition, and then cooled to obtain a latex.
[0117] The polymerization conversion rate was 99.8%. Use calcium chloride aqueous solution to make the obtained latex salt-out and solidify, after heating up to 90°C for heat treatment, use a centrifugal dehydrator to filter and wash the dehydration filter cake (dehydration ケ-キ) of the resulting copolyme...
Synthetic example 2
[0119] 200 parts of distilled water and 0.5 parts of sodium dioctyl sulfosuccinate were added to an 8-liter reaction vessel equipped with a stirrer and a cooler. Then, after replacing the inside of the container with nitrogen, the temperature of the reaction container was raised to 70° C. while stirring. Then add 0.2 parts of potassium persulfate and stir for 15 minutes, then continuously add the mixture of 90 parts of GMA, 3 parts of MMA, 7 parts of BA and 1.0 TDM within 4.5 hours, stir for 1 hour after the addition, and then cool to obtain latex.
[0120] The polymerization conversion rate is 99.4%. Calcium chloride is used to salt out and solidify the obtained latex. After heating up to 90°C for heat treatment, it is filtered with a centrifugal dehydrator, and the dehydrated filter cake of the obtained copolymer is washed with water. Drying at 50°C for 15 hours gave a white powdery first-stage polymer sample (7).
