摘要：

Treated waste pulp (Pulp) was used as cellulosic material. Water-soluble cellulose (PSAAc) was synthesized by acetylation of cellulose succinate. Composite films were prepared from PSAAc and polyvinylalcohol (PVA) by a casting method, and crosslinked by heating or reacting with hexamethylene diisocyanete (HDI). These films were homogeneous and transparent. Three types of homogeneous films: non-treated film, HDI-treated film, and heat-treated film, and heterogeneous film obtained from Pulp and PVA were used for tensile strength test and biodegradation test. HDI-treated film showed the highest elongation (592%). On the other hand, the heat-treated film and the heterogeneous film were fragile. The biodegadation test in soil gave the following order of weight loss for composite films: heterogeneous film > non-treated film > HDI-treated film > heat-treated film.
