The results show that the glass-ceramics with fibroid structure is produced after definite heat treatment, the main crystallization phase is hedenbergite and anorthite is the minor crystallization phase. The optimal process of heat treatment shows as follows: the nucleation temperature is 850 ℃ and hold time is 100 min, and the crystallization temperature is 980 ℃ and hold time is 80 min. With increasing heat treatment temperature, the FT-IR absorption bands appear obvious split, the aluminum-oxide polyhedron in the glass network changes from [AlO4] to [AlO6]. The titanium ion in the glass network gradually transforms to the 6-coordinated, moreover forms minicrystal of MgTi2O5 and Fe2TiO4 which provides the position of heterogeneous nucleation for the growth of crystal.

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.

The results showed that the m-PUE had better heat-resistant properties, lower glass transition temperature, higher thermal decomposition temperature and better damping property. The internal friction peak was changed from 10 ℃ to -10 ℃, while the tan δ was changed from 0.28 to 0.46. The hardness, tensile strength and tear strength of m-PUE decreased with the increase of the THEIC content. However, the swelling ratio of PUE was increased meaning a deteriorated solvent resistance property.
