摘要:
The viscosity stability of hot melt adhesives containing an elastomeric linear EPDM, branched ethylene/propylene copolymer, or propylene/hexene-1 dipolymer is markedly improved by inclusion in the adhesive composition of boric acid, boric anhydride, or a boric acid ester, in combination with a phenolic antioxidant.
