        摘要：This paper reviews the synthesis and characterization of hydrophobically associating water-soluble polymers. It present the synthetic routes designed to overcome the problems of mixing and reacting oil-soluble and water-soluble monomers, and methods for determining the amounts of hydrophobe incorporated by NMR, UV and degradation/GC.

        摘要：Gas-Assisted Injection Molding (Gaim) is an innovative molding technology where the compressed gas is introduced into the mould to create hollow sections,to pressurize plastics during cooling,to eliminate shrinkage and to complete mould filling. Compared with a conventional injection molding,Gaim process presents many advantages and benefits such as reducing the moulding weight, reducing the molding circle,avoiding the sink marks. This technology has been widely used in abroad in the field of TV sets and other appliances, cars, furniture, etc. However, gaim process concerns within the mould with a two - phase complex flow of molten polymer and pressurized gas. Computer aided flow analysis is very important in achieving successful applications with the complications in part, mould and process design.
