N2-phosphinyl amidine compounds, N2-phosphinyl amidinates, N2-phosphinyl amidine metal salt complexes, N2-phosphinyl amidinate metal salt complexes are described. Methods for making N2-phosphinyl amidine compounds, N2-phosphinyl amidinates, N2-phosphinyl amidine metal salt complexes, and N2-phosphinyl amidinate metal salt complexes are also disclosed. Catalyst systems utilizing the N2-phosphinyl amidine metal salt complexes and N2-phosphinyl amidinate metal salt complexes are also disclosed along with the use of the N2-phosphinyl amidine compounds, N2-phosphinyl amidinates, N2-phosphinyl amidine metal salt complexes, and N2-phosphinyl amidinate metal salt complexes for the oligomerization and/or polymerization of olefins.
Aldimines of Formula (I), which can be used as latent curing agents in curing compositions, for example, in moisture-curing polyurethane compositions that have isocyanate groups. The aldimines are compounds that can be liquid at room temperature, can have a hardly noticeable aldehyde odor before, during and after hydrolysis, and can have a long shelf life. An aldehyde in polyurethane compositions that is released during hydrolysis has only a slight softening effect and can exhibit very little tendency to migrate or exude.

A prepreg includes; sizing agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic compound (B) at least containing an aromatic epoxy compound (B1). The thermosetting resin composition includes a thermosetting resin (D) and a latent hardener (E), and optionally includes an additive (F) other than the thermosetting resin (D) and the latent hardener (E). The (a)/(b) ratio is within a predetermined range where (a) is the height of a component at a binding energy assigned to CHx, C—C, and C═C and (b) is the height of a component at a binding energy assigned to C—O in a C

To provide a prepreg and a carbon fiber reinforced composite material that are excellent in adhesion between a matrix resin and carbon fibers and long-term storage stability and also excellent in microcrack resistance due to the increased toughness. The present invention provides a prepreg that includes; agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic epoxy compound (B1). The sizing agent-coated carbon fibers are in a shape of woven fabric or braid. The thermosetting resin composition includes a thermosetting resin (D), a thermoplastic resin (F), and a latent hardener (G). The sizing agent-coated carbon fibers have an (a)/(b) ratio in a certain range where (a) is the height of a component at a binding energy assigned to CHx, C—C, and C═C and (b) is the height of a component at a binding energy assigned to C—O in a C
