This paper described a pilot process of polymerization of acrylamide in middle conce-ntration (30~35% by weight) aqueous solution with the additive disodium EDTA. Thewhole process is divided into four parts: 1. The preparation system (including preparation of monomer, additive and other things before irradiation). 2. The transportation system (for carring monomer and product). 3. The radiation polymerization system (including γ-rays irradiation facilities). 4. The product treatment system. The intensity of ~(60)Co source used was 45000Ci and the polymerization capacity ofthis set is about 30 ton/year now. There are three kinds of products: non-ionic, ionicand crosslinking. They have successfully been used in petroleum, metallurgy, coal, andother fields, Good results were ohtained.

A series of polylactide-poly(ethylene glycol)(PLA-PEG) block copolymers,covering a wide range of PEG segmental lengths, was synthesized with SnCl2· 2H2O catalyst and Al(i-Bu)3-H2O-H3PO4 complex catalyst. Their morphology was investigated by means of DSC and TEM studies. The effects of polymer treatment,chain length of PEG and fractionation of the copolymer on morphological structure were discussed. The results show that the copolymers made from two catalysts exhibited a quite different morphology.
