Abstract
Aliphatically modified rosin resins are prepared by reacting rosin esters with aliphatic monomers. These aliphatically modified rosin resins are compatible with metallocene catalyzed polyolefins and other aliphatic base polymers and are used as tackifiers in combination with metallocene catalyzed polyolefins and other aliphatic base polymers to form adhesive compositions for hot melt and pressure sensitive applications.
Claims21
A method of producing an aliphatically modified rosin resin comprising the steps of:
- esterifying a rosin by reaction with a polyol to produce a rosin polyol ester and
- reacting said rosin polyol ester with a monomer material to produce said aliphatically modified rosin resin,
- wherein said monomer material is selected from:
- C6 to C22 alpha-olefins;
- vinyl-terminated ether monomers;
- C6 to C22 alpha-beta unsaturated esters and acids;
- fumaric, maleic, or acrylic esters or diesters of C4 to C22 aliphatic chains or rings;
- and combinations thereof.
A thermoplastic adhesive composition comprising an aliphatic base polymer material and an aliphatically modified rosin resin produced by (a) esterifying a rosin by reaction with a polyol to produce a rosin polyol ester and (b) reacting said rosin polyol ester with a monomer material to produce said aliphatically modified rosin resin, wherein said monomer material is selected from:
- C6 to C22 alpha-olefins;
- vinyl-terminated ether monomers;
- C6 to C22 alpha-beta unsaturated esters and acids;
- fumaric, maleic, or acrylic esters or diesters of C4 to C22 aliphatic chains or rings;
- and combinations thereof.
A thermoplastic adhesive composition comprising a metallocene catalyzed polyolefin and an aliphatically modified rosin resin produced by (a) esterifying a rosin by reaction with glycerin to produce a rosin glycerin ester and (b) reacting said rosin glycerin ester with 1-decene.
