Title:
CAGE-LIKE SILOXANE-CONTAINING POLYMER, CAGE-LIKE SILOXANE, AND METHOD FOR PRODUCING THE SILOXANE
Document Type and Number:
Japanese Patent JP2021161226
Kind Code:
A
Abstract:
To manufacture and develop a silsesquioxane structure-containing polymeric compound having extremely high heat resistance and good mechanical properties.SOLUTION: A cage-like siloxane-containing polymer having high heat resistance and mechanical strength is obtained by polymerizing a cage-like siloxane compound whose stereo isomer ratio is controlled, and a straight chain siloxane compound. The cage-like siloxane compound whose stereo isomer ratio is controlled is manufactured by enriching an isomer by crystallizing a cage-like siloxane diol and silylating the enriched isomer.SELECTED DRAWING: None
