Document Type and Number:
Japanese Patent JP5138150
Kind Code:
B2
Abstract:
Aqueous dispersions of one or more biodegradable polymers comprising an organic phase dispersed in an aqueous dispersing phase and free from volatile organic solvents in which the organic phase comprises at least one viscosity reducing agent with specified solubility and hydrogen bond parameters and one or more biodegradable polymers. Aqueous dispersions of one or more biodegradable polymers comprising an organic phase dispersed in an aqueous dispersing phase and free from volatile organic solvents in which the organic phase comprises at least one viscosity reducing agent with specified solubility and hydrogen bond parameters and one or more biodegradable polymers. The viscosity reducing agent (plasticizer) has a solubility parameter 15-28, more preferably 16-23 and most preferably 18-21 (J.cm -> 3>) 0>.5 and a hydrogen bond parameter delta H 3.5-15, more preferably 4-13 and most preferably 5-10 (J.cm -> 3>) 0>.5. The ratio by weight of polymer to plasticizer is 99.8/0.2 to 60/40, more preferably 97/3 to 70/30 and most preferably 92/8 to 70/30. Independent claims are included for (1) a method of preparing the claimed dispersions comprising the steps of preparing the organic phase melting the mixture of polymer and plasticizer at a temperature above the glass transition temperature of the polymer so as to obtain a homogeneous mixture, totally solubilizing the stabilizer in the aqueous phase, introducing the two phases simultaneously into a mixer in the desired ratio and recovering the dispersion obtained; (2) the use of the claimed dispersions for their binding/gluing, printability, degradability, water resistance, brilliance, oil resistance, stain resistance and mechanical resistance properties.
