Title: Synthese de poly(propylene fumarate) par acylation de propylene glycol en presence d'un intercepteur de protons
Inventor: MIKOS ANTONIOS G
IPC: A61L24/00
Filed: 1999-04-09
Abstract: L'invention a trait à un poly(propylène fumarate) linéaire de poids moléculaire élevé présentant un indice de polydispersion relativement faible qu'on obtient en utilisant un produit intermédiaire relativement pur, et à un procédé de fabrication de celui-ci. Du chlorure de fumaryle et du propylène glycol sont mis à réagir en présence de carbonate de potassium. Le carbonate de potassium présent dans la solution de réaction permet d'empêcher le sous-produit d'acide de provoquer des réactions de catalyse à la liaison double du fumarate. Le bis(propyl fumarate) produit selon cette technique peut être transestérifié par des étapes de traitement classiques pour obtenir du P(PF). Le P(PF) produit à partir de bis(propyl fumarate) produit selon la présente invention présente un poids moléculaire plus élevé, et est plus pur que du P(PF) produit à l'aide de techniques connues antérieurement.

Abstract: Latency in receiving and detecting paging messages at a wireless terminal is reduced by employing a unique "super" paging time slot format. A paging super time slot includes a plurality of prescribed time slots. Each wireless terminal is associated with cyclically recurring super time slots. A super slot is associated with one or more wireless terminals. A base station always selects the first available time slot in a super time slot to transmit a paging message to a wireless terminal that is associated with the super time slot. Each wireless terminal monitors every time slot in the associated super time slot until either detecting reception of its associated paging message or detecting an empty time slot. In another embodiment of the invention, a unique partially overlapping super time slot format is employed in which a super time slot has at least one time slot common to its adjacent super time slots. This. allows wireless terminals associated with adjacent super time slots to share the common at least one time slot. In turn, this results in balanced traffic loads, smoothed traffic fluctuation and reduced congestion.
