        摘要：The importance for developing and strengthenning the study on natural polymer has been discussed on the strategy viewpoint of resources utilization in this paper. Several natural polymers have been used as example to discuss the tendency and advance of the study. To compare with synthetic polymer, the problems in natural polymer study have been pointed out. The excellent works in this field contributed by Chinese scientists are briefly introduced.

        摘要：Recent development of waterborne polyurethanes (PU) at home and abroad were reviewed in a systematic way, according to its syntheses, aqueous dispension and film perporties. Moreover,perhaps most importantly,the quality of these waterborne PU has made them very suitable for a myriad of application areas.

        摘要：The varieties in environmental responses of polymeric surfaces were described. The responsibilities could be controlled via surface modifications and formation of multi - component polymers with different structural parameters effectively. There are correlations in responsibility with blood compatiblilty of biomedical materials and responsibility with intelligent behavior of adhesives suiting for both polar and non - polar substrates.

        摘要：The positive or negative PS plate is characterized by its photodecomposition or photocrosslinking under exposure respectively. The positive PS plate is being used extensively rather than negative PS plate in China. The negative PS plate prepared from substituted dipheny- lamine diazoresin possesses good thermostability as well as long storage - life.

        摘要：High water absorbent resin can absorb several hundred times and several thousand times as much water as its own weight, owning to its high capacity for absorbing water, high degree of water retention under pressure,High water absorbent resin was a three - dimensional network polymer, it was polyelectrolytes. Polymer chains making up the network cantain ioniz- able group and mobile electrolyte ions. The concentration of mobile ions will always be greater in the gel than outside because, Consequently the osmetic pressure of solution inside will exceed that of the external solution. The water absorbem mechanisms of high absorbent resin was explicated by thermodynamic formulation of Flory - Hoggins.
