Conclusion：
1, the preparation process that RAFT activity polymerizating technologies are combined with mini-emulsion polymerization is all made of in Examples 1 to 4, by table
5 middle-molecular-weihydroxyethyl test results can be seen that binder latex film strand is in apparent three block structure, and molecular weight controllability is good；With
The increase of soft monomer ratio, soft polymer molecular weight is in accordingly that proportional linearity increases in Examples 1 to 4, causes binder
The enhancing of latex film stickiness, elasticity reduce, and corresponding to then being shown as in mechanical property, stress reduces, strain increases.Show to bind
The soft epistasis of agent latex film can be controllable.
2, it is all made of conventional mini-emulsion polymerization technique in comparative example, binder can be seen that by 6 middle-molecular-weihydroxyethyl test result of table
Latex film is without feature chain structure, and molecular weight atactic is then, shows that polymer chain architecture is uncontrollable；Stress-strain data is random,
And it is generally poor compared with embodiment result.
