Claims27
A method of producing a rosin ester, the method comprising:
- (A) Contacting a rosin having PAN isomers with disproportionation agent to provide a rosin having a PAN number less than 45 providing a disproportionated rosin;
- (B) Contacting the disproportionated rosin with an adduction agent to further reduce the PAN number to provide an adducted rosin;
- (C) Contacting the adducted rosin with a polyhydric polyol to form a rosin ester.
A method of producing a rosin ester, the method comprising:
- (A) Contacting rosin having a PAN number less than 45 with an adduction agent to further reduce the PAN number to provide an adducted rosin;
- (B) Contacting the adducted rosin with a polyhydric polyol to form a rosin ester.
A rosin ester composition having an odor intensity of less than 80% relative to comparison rosin ester made from 100% pentaerythritol.
An adhesive comprising a rosin ester composition having an odor intensity of less than 80% relative to comparison rosin ester made from 100% pentaerythritol.
A non-woven product comprising an adhesive comprising a rosin ester composition having an odor intensity of less than 80% relative to comparison rosin ester made from 100% pentaerythritol.
