Abstract: This invention relates to the separation of crude mixtures of sterols, and more particularly it relates to the removal of stigmasterol derived products from crude mixtures of sterols. The present invention relates more specifically to a process for separating stigmasterol-derived products from phytosterol materials containing mixtures of stigmasterol, sitosterol and campesterol. These mixtures are reacted to form the corresponding mixture of phytosterol i-methyl ethers. The mixed phytosterol i-methyl ethers are reacted by ozonolysis to form the stigmasterol-derived aldehyde material, 6-.beta.-methoxy-3.alpha.,5.alpha.-cyclodinorcholanaldehyde, which can be isolated from the phytosterol i-methyl ethers by either chromatography or by treatment with sodium bisulfite and extraction with a suitable organic solvent such as toluene.

Abstract: This invention relates to blends of compatible tackifiers with substantially amorphous olefin copolymers containing at least one C.sub.3 to C.sub.5 linear .alpha.-olefin and 40 to 60 mole percent of at least one C.sub.6 to C.sub.10 linear .alpha.-olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer base resins have melt viscosities in the range of >75,000 cp up to about 1,000,000 cp at 190.degree. C. The addition of the compatible tackifiers to the copolymer base resin causes a dramatic and unexpected increase in the shear adhesion failure time in addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.
