POLYMER COATED PARTICULATE COMPOSITIONS AND RELATED METHODS AND APPLICATIONS

The polymer coated microparticles can be prepared by melt emulsification methods, for example, by: forming a mixture comprising a carrier fluid, microparticles, a thermoplastic polymer, and an optionally an emulsion stabilizer to be mixed to a mass ratio of thermoplastic polymer of about 1 : 0.1 to...

Beschreibung
Zusammenfassung:	The polymer coated microparticles can be prepared by melt emulsification methods, for example, by: forming a mixture comprising a carrier fluid, microparticles, a thermoplastic polymer, and an optionally an emulsion stabilizer to be mixed to a mass ratio of thermoplastic polymer of about 1 : 0.1 to about 1 : 5 at a temperature above the melting point or softening temperature of the thermoplastic polymer; cooling the mixture below the melting or softening temperature to form polymer coated microparticles; and separating the polymer coated microparticles from the carrier fluid. 중합체 코팅된 미립자는 용융 유화 방법에 의해, 예를 들어, 담체 유체, 미립자, 열가소성 중합체, 및 선택적으로 에멀젼 안정제를 포함하는 혼합물을 열가소성 중합체의 융점 또는 연화 온도 이상의 온도에서, 미립자 대 열가소성 중합체의 질량비를 약 1:0.1 내지 약 1:5로 혼합하는 단계; 혼합물을 융점 또는 연화 온도 미만으로 냉각시켜 중합체 코팅된 미립자를 형성하는 단계; 및 중합체 코팅된 미립자를 담체 유체로부터 분리하는 단계에 의해 생성될 수 있다.
