Title:
【発明の名称】一酸化炭素と不飽和化合物のポリマーの調製
Document Type and Number:
Japanese Patent JP2963531
Kind Code:
B2
Abstract:
A mixture of two linear polymers 1 and 2 of carbon monoxide with one or more olefinically unsaturated compounds, in which on the one hand the units from carbon monoxide and on the other hand the units from the olefinically unsaturated compound(s) are present in substantially alternating fashion, is prepared by contacting the monomers at elevated temperature and pressure with a suitable catalyst, and a) carrying out the preparation of polymer 1 at a set temperature T1, b) carrying out the preparation of polymer 2 at a set temperature T2, which is 3-30 DEG C lower than the temperature T1, and c) carrying out the preparation of polymer 2 in the presence of such a quantity of polymer 1 that the thus obtained polymer mixture contains 3-45 %w of polymer 1. e
