WERKWIJZE VOOR DE BEREIDING VAN ONDER DIREKTE INWERKING VAN ZONLICHT AFBREEKBARE POLYMEREN DOOR TOEVOEGING VAN AFBRAAK-BEVORDERENDE STOFFEN, EN DAARUIT VERVAARDIGDE GEVORMDE VOORTBRENGSELEN.

摘要

A novel process for making polymers degradable by the direct action of sunlight is disclosed. The process is based on the addition to the polymer of a compound having the formula: R2R3 ANGLE C= C ANGLE R1R4 in which R1, R2, R3 and R4 are the same or different and are selected from the group consisting of aromatic radicals with the proviso that one or two of them may be selected from the group consisting of hydrogen, alkyl, cycloalkyl and arylalkyl.
