The thermal stabilization of the composite was improved compared to those of as-polymerized PLLA and Al(OH)3 themselves, which makes the melt processing of the composite easier. Nevertheless, at temperatures lower than 300°C the effective depolymerization of PLLA proceeded, without any racemization reaction, to selectively convert into L,L-lactide, with Al(OH)3 acting as a catalyst for the depolymerization. This means that the PLLA/Al(OH)3 composite is capable of reconciling flame resistance with feedstock recycling of PLLA to cyclic monomer.}, pages = {1433--1437}, title = {Feedstock Recycling of Flame-Resisting Poly(lactic acid)/Aluminum Hydroxide Composite to L,L-lactide}, volume = {44}, year = {2005}, yomi = {ニシダ, ハルオ and シライ, ヨシヒト and エンドウ, タケシ} }
