Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

The hydrolysates from oat xylan using Xyn Ⅰ Xyn Ⅱ and their mixture for hydrolysis were analysed by HPLC. It was showed that Xyn Ⅰ hydrolyzed mainly the unsubstituted regions of oat xylan, and hydrolytes were high xylooligosaccharides; whereas Xyn Ⅱ exhibited greater catalytic versatility than Xyn Ⅰ and were able to attack substituted regions of the polysaccharide and showed greater activity to low xylooligosaccharides than Xyn Ⅰ to give xylobiose as the main hydrolysate. The purified xylanases were acidic enzymes.
