The invention relates to a multilayered material sheet comprising a consolidated stack of unidirectional monolayers of drawn polymer. The draw direction of two subsequent monolayers in the stack differs. Moreover the strength to thickness ratio of at least one monolayer is larger than 4.5.10N/m. The invention also relates to a ballistic resistant article comprising the multilayered material sheet and to a process for the preparation of the ballistic resistant article.

Multilayered material sheet and process for its preparation

The invention relates to ballistic resistant article having a multilayered material sheet which includes a consolidated stack of unidirectional monolayers of drawn polymer, whereby the draw direction of two subsequent monolayers in the stack differs. At least one monolayer comprises a plurality of unidirectional tapes of the drawn polymer, aligned in the same direction, whereby adjacent tapes do not overlap. The invention also relates to a process for the preparation of the multilayered material sheet, and to a ballistic resistant article comprising the multilayered material sheet.

The invention relates to a process for the isolation of an organic amine from a composition comprising the organic amine and an acid, or a salt of the organic amine and the acid, wherein the process comprises steps wherein ammonia or hydrazine is added to the composition thereby forming a multi-phase system comprising an organic amine-rich phase and an acid-rich phase, the organic amine-rich phase and the acid-rich phase obtained in step (i) are separated, and the organic amine is isolated from the organic amine-rich phase.

Process for isolation of an organic amine

Process for the catalytic hydrogenation of a nitrite in the presence of an amine and a catalyst wherein the catalyst is a liquid-rinsed Raney-type catalyst contacted with a hydroxide prior to contacting the catalyst with the amine. The process results in higher selectivity in the formation of diamines from diniriles.
