Abstract: The present invention refers to a resin composition comprising an ester compound and a polymer, wherein the ester compound and the polymer are obtainable by reacting a diene, a dienophile and a carboxylic acid. The invention also refers to adhesive compositions comprising the resin composition.

Abstract: The invention relates to a novel polyester tackifier, adhesive compositions comprising the tackifier and methods of preparation. More specifically, the polyester tackifier is obtainable by polymerising a mixture comprising a diacid or derivative thereof, a diol, and at least 6 molar % of an organic monofunctional compound, wherein the mixture is essentially free from compounds comprising more than two carboxylic acid groups or alcohol groups.

Abstract: The invention relates to a tackifier dispersion comprising a resinous material and an emulsifier, the emulsifier being obtainable by a method comprising providing an ester of one or more fatty acids containing at least two conjugated double bonds, reacting the ester with a dienophile containing an acid or anhydride group, to form an intermediate product A, and, reacting the intermediate product A with one or more polyalkylene glycols. The invention also relates to a method for the production of a tackifier dispersion, its use as a tackifier, and an adhesive composition comprising the tackifier dispersion. The invention further relates to an emulsifier, a method of producing the same and its use for emulsifying resinous materials.

Abstract: A process of converting linear olefins to branched olefins by a skeletal isomerization reaction wherein said reaction is carried out at a temperature of between about 300.degree. C. and about 650.degree. C., under a pressure of between about 0.1 and about 100 atmospheres and a space velocity of said linear olefins of between about 0.1 and about 40 WHSV in the presence of a steamed then acid washed zeolite ferrierite catalyst.

Abstract: The method of converting n-butylenes to isobutylene by a skeletal isomrization reaction wherein said reaction is carried out at a temperature of between 300.degree. C. and 650.degree. C., under a pressure of between 0.1 and 100 atmospheres and a space velocity of said n-butylenes of between 0.1 and 40 WHSV using a cagalyst comprising a zeolite binder selected frm the group consisting of alumina, silica, silica-alumina, clay and a combination thereof, said catalyst having a pore size of at least about 4.5 angstroms and the pore size structure is characteried by intersecting 10-member ring and 8-member ring channels.

Abstract: The conversion of normal olefins such as n-butylenes can be converted to branched olefin species such as isobutylene by skeletal isomerization over zeolite-based catalysts having pore sizes of at least about 4.5 Angstroms and a pore structure characterized by intersecting 10-MR and 8 MR channels. The zeolite-based catalysts have sufficient acidity to catalyze the skeletal isomerization of normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.

Abstract: Normal olefins such as n-butenes can be converted to iso olefins such as isobutylene by skeletal isomerization over catalysts of boron-beta zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The boron-beta zeoliteS have sufficient acidity to catalyze the skeletal isomerization of normal olefinsto iso-olefins. The catalysts can be used to produce iso-olefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.

Abstract: Normal olefins such as n-butenes and normal alkanes such as n-butane can be coverted to branched olefin species such as isobutylene by skeletal dehydroisomerization over catalysts preferably containing metals selected from Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, VIII and the rear earth elements which are deposited upon borosilicate zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The borosilicates have sufficient acidity to catalyze the skeletal isomerization of both normal alkanes and normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.
