Abstract
There is provided a method for producing a resin composition which is good in dispersability of a biodegradable resin. This method has a first kneading step of kneading (A) a biodegradable resin and (B) a compound that is reactive with the biodegradable resin (A) to produce a resin composition precursor, and a second kneading step of kneading the resin composition precursor and a polyolefin resin (C).
Claims7
A method for producing a resin composition containing (A) a biodegradable resin and (C) a polyolefin resin, wherein the method comprises:
- a first kneading step of kneading the biodegradable resin (A) and (B) a compound that is reactive with the biodegradable resin (A) to produce a resin composition precursor, and
- a second kneading step of kneading the resin composition precursor and the polyolefin resin (C), wherein in the first kneading step, (D) an elastomer is further added and kneaded prior to the formation of the resin composition precursor.
