摘要
以偶氮二异丁腈为引发剂,采用紫外光引发聚合方法制备玉米淀粉-丙烯酸丁酯接枝聚合物。通过改变光照引发时间、引发剂用量和反应时间等条件可得到具有不同接枝率的聚合物。不同组成的玉米淀粉-丙烯酸丁酯接枝聚合物与尿素制成的缓释尿素片均具有缓释性能,其中接枝率较高的聚合物载体表现出更好的缓释效果。
Corn starch-n-butyl acrylate graft polymers were synthesized via a photo-initiated polymerization using azobisisobutyronitrile as photo-initiator. Polymers with various graft rates were obtained by controlling photo-initiation time,initiator dosage and reaction time. The tablets consisted of these graft polymers and urea exhibited slow releasing properties. The polymer with higher graft rate displayed better slow releasing effect.
