Abstract
The invention provides a decomposable resin composition, which is stable at the time of use and which quickly decomposes when discarded. According to the present invention, there is provided a resin composition comprising an agent generating an acid or a base upon response to light or heat together with a hydrolyzable and biodegradable resin. The decomposable resin composition can promote decomposition of the polymer by generating an acid or a base in the resin by carrying out light irradiation and/or a heat treatment at a desired time and can control the decomposition speed of the polymer by controlling the generation amount of an acid or a base.
Claims5
A resin composition comprising an agent generating an acid by heating and/or an agent generating a base by heating in a hydrolyzable and biodegradable resin, which has the following structure:
- wherein (Sacch) denotes a saccharide structure and R denotes a group formed by removing two carboxylic groups from aliphatic or aromatic dicarboxylic acid.
A resin composition comprising an agent generating an acid by light and/or an agent generating a base by light together with an agent generating an acid by heating and/or an agent generating a base by heating in a hydrolyzable and biodegradable resin, which has the following structure:
- wherein (Sacch) denotes a saccharide structure and R denotes a group formed by removing two carboxylic groups from aliphatic or aromatic dicarboxylic acid.
A method of treating a resin composition comprising the steps of:
- providing the resin composition comprising an agent generating an acid by heat and/or an agent generating a base by heat in a hydrolyzable and biodegradable resin;
- and
- subjecting the resin composition to heat treatment, wherein the hydrolyzable and biodegradable resin has the following structure:
- wherein (Sacch) denotes a saccharide structure and R denotes a group formed by removing two carboxylic groups from aliphatic or aromatic dicarboxylic acid.
