摘要： Provided are: a resin modifier with which flexibility, transparency and bleed resistance can be balanced at a high level; a resin composition; and a film using the same. The resin modifier includes a random copolymer composed of a structural unit derived from an aliphatic dibasic acid, a structural unit derived from an alkylenediol, and a structural unit derived from a polyalkylene ether glycol, which random copolymer has a hydroxyl group or a carboxyl group at a terminal. The polyalkylene ether glycol is preferably a polyethylene ether glycol, and the alkylenediol is preferably at least one selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propanediol, 2-methyl-1,3-propanediol, 1,3-butanediol, 1,4-butanediol, neopentyl glycol, 3-methyl-1,5-pentanediol, and hexanediol.

摘要： Provided is a cellulose resin composition wherein roll contamination during processing and reduction in the productivity caused by roll contamination are inhibited. The cellulose resin composition is obtained by adding a polyester-based plasticizer to a cellulose resin, the cellulose resin composition being characterized in that the polyester-based plasticizer is produced from a polybasic acid, a polyhydric acid and, as required, a stopper, in which polyester-based plasticizer, components having a molecular weight of 430 or less are removed to an amount of 5 wt% or less.

摘要： Provided are a cellulose resin composition which can give a cellulose ester film free from the problems with bleeding and has excellent moisture permeability, even when containing a plasticizer in a relatively large amount, and a cellulose resin film which is obtained from the cellulose resin composition.
The present invention relates to a cellulose resin composition obtained by adding (A) a polyester plasticizer to a cellulose resin. The aforementioned (A) polyester plasticizer is obtained from a polybasic acid, a glycol and a stopper, wherein 70 to 30 mol% of the aforementioned polybasic acid is a succinic acid and/or an adipic acid; 30 to 70 mol% of the aforementioned polybasic acid is at least one selected from a group consisting of a terephthalic acid, a phthalic acid and an isophthalic acid; the aforementioned glycol is at least one selected from a group consisting of an ethylene glycol, a 1,2-propylene glycol, a 1,3-butanediol and a 2-methyl-1,3-propanediol; the aforementioned stopper is an acetic acid and/or a benzoic acid; and the weight-average molecular weight is 600 to 2,000.
