Beschreibung
Zusammenfassung:	Methods for polymerization of phosphaalkenes using initiators are provided. Also provided are polymers and co-polymers in which the polymer backbone contains tracts of carbon and phosphorus atoms in approximately equimolar amounts. C-P bonds in the polymers of this invention may be predominantly in a head-to-tail arrangement or mixed arrangements. Co-polymers may comprise polyolefin monomer units. L'invention concerne des procédés de polymérisation d'alcènes phosphorés faisant intervenir des amorceurs. L'invention concerne également des polymères et des copolymères dans lesquels le squelette polymère contient des atomes de carbone et de phosphore en quantités approximativement équimolaires. Les liaisons C-P dans les polymères de cette invention peuvent être disposés principalement en tête et en queue ou de manière mélangée. Les copolymères de l'invention peuvent comprendre des unités monomériques polyoléfiniques.
