Pilot Production of Polyglycolide;

Copolymerization of Glycolide with Lactide and Measurement of Reactivity Ratios;

Study on the Synthesis of Biodegradable Raw Material glycollide by Ultrasound;

In order to improve the water affinity of PLLA andcontrol its degeneration speed, the lactide (LLA) was copolymerizedwith glycollide(GA).

In this paper, firstly lactide, glycollide and their copolymer(PGLA) were summarized, primarily involved their basal performance, method of their synthesize, actuality of their development.

Effect of spinning velocity on structure of polyglycollide fiber;

Study on rheological behavior of polyglycollide and poly(glycolide lactide);

Finally, the glycolide was twice purified and polymerized into polyglycolide by a ring opening polymerization.

Rope-like three-dimensional (3D) braids were prepared from chitosan and polyglycolide(PGA)fi- bers by means of 4-step 3D tubular braiding technique.

In this study, polyglycolide (PGA) fibers w.

Research on the Manufacturing Techniques of Biodegradable Polymer PLGA Particle;

To prepare the poly(d,l-lact ic-co-glycolic acid)(PLGA)sustained-release microspheres loaded with all-trans retinoic acid(ATRA),and detect microspheres shape,size,the drug loading,encapsulation efficiency,the release of drugs in vitro and the determination of blood Concentration in vivo.
