NOVEL HIGH-MOLECULAR-WEIGHT COMPOUND WITH HIGH STIFFNESS AND TOUGHNESS

PURPOSE:A novel type of high polymer that has specific recurring units, thus being suitably used as a modifier of vinyl polymers for general purposes, because it is low flexibility, high stiffness and can be readily produced. CONSTITUTION:Preferably, di-t-butyl fumarate is radically polymerized to g...

Zusammenfassung:	PURPOSE:A novel type of high polymer that has specific recurring units, thus being suitably used as a modifier of vinyl polymers for general purposes, because it is low flexibility, high stiffness and can be readily produced. CONSTITUTION:Preferably, di-t-butyl fumarate is radically polymerized to give a new type of high polymer which has the major chain of t-butoxy-carbonyl methylene chain represented by the formula, preferably with a number-average molecular weight of 5,000-300,000.
