摘要:
A biodegradable polyester resin composition which comprises a thermoplastic polymer comprising 100 parts by mass of an aliphatic polyester (A) and 0.01 to 5 parts by mass of a (meth)acrylic ester (B1) and/or a glycidyl ether (B2, and has a gelation index (1) of not lower than 0.1% and a gelation index (2) of not higher than 0.5%.
摘要:
Disclosed is a biodegradable polyester resin composition which is obtained by melt-kneading 100 parts by mass of a biodegradable polyester resin (A) containing 70 mol % or more of an α- and/or a β-hydroxycarboxylic acid unit, 3 to 30 parts by mass of a polyether/olefin block copolymer resin or a polyether ester amide copolymer resin (B), 0.01 to 10 parts by mass of a (meth)acrylic acid ester compound (C) having in the molecule thereof two or more (meth)acrylic groups, or alternatively one or more (meth)acrylic groups and one or more glycidyl or vinyl groups, and 0.01 to 10 parts by mass of a peroxide (D).
摘要:
Disclosed is a foam sheet made of a biodegradable resin composition. The biodegradable resin composition contains a wax and/or a polyolefin resin. The biodegradable resin is mainly composed of polylactic acid. Natural candelilla wax or paraffin wax is preferable as the wax. Polyethylene is preferable as the polyolefin resin. Also disclosed are a foam article and a molded container made of such a foam sheet wherein the degree of crystallinity of the biodegradable resin is 10% or more.
