A method for producing a &#x3b2;-alkoxypropionamide shown by the following formula (I) including the step of reacting a &#x3b2;-alkoxypropionic acid ester with an amine in the presence of a basic catalyst or in the presence of a basic catalyst and a polyol: wherein Ris an alkyl group having 1 to 8 carbon atoms, and Rand Rare independently hydrogen, a methyl group, an ethyl group, a methoxy group, an ethoxy group, a methoxymethyl group or a glycidyl group.

Method for producing a &#x3b2;-alkoxypropionamide

A 1-butene polymer satisfying the following (1), (2) and either (3) or (3'): a process for producing the polymer; a resin modifier comprising the polymer; and a hot-melt adhesive containing the polymer. (1) The intrinsic viscosity [&#x3b7;] as measured in tetralin solvent at 135&#xb0; C. is 0.01 to 0.5 dL/g. (2) The polymer is a crystalline resin having a melting point (Tm-D) of 0 to 100&#xb0; C., the melting point being defined as the top of the peak observed on the highest-temperature side in a melting endothermic curve obtained with a differential scanning calorimeter (DSC) in a test in which a sample is held in a nitrogen atmosphere at &#x2212;10&#xb0; C. for 5 min and then heated at a rate of 10&#xb0; C./min. (3) The stereoregularity index {(mmmm)/(mmrr+rmmr)} is 30 or lower. (3&#x2032;) The mesopentad content (mmmm) determined from a nuclear magnetic resonance (NMR) spectrum is 68 to 73%.

Highly flowable 1-butene polymer and process for producing the same

The present invention provides a process of an industrially advantageous production of high-purity adamantane at a low cost and with a high efficiency by isomerizing trimethylenenorbornane contained in a raffinate obtained from a platfinate.

Process for producing adamantane

Provided are a high melting point copolymer prepared by heat-polymerizing cyclopentadiene and/or dicyclopentadiene and a vinyl-substituted aromatic compound, wherein a use amount of a solvent in heat polymerization is 0.1 time or more and less than 0.5 time based on the mass of the whole monomers, and the copolymer has a softening point falling in a range of 100 to 135&#xb0; C., and a hydrogenated copolymer obtained by hydrogenating the above high melting point copolymer. The hydrogenated copolymer of the present invention is suitably used as an adhesion-providing resin having a high softening point for a hot melt adhesive.
