  • POLYMERS OF INTRINSIC MICROPOROSITY (PIMS) CONTAINING LOCKED SPIROBISINDANE STRUCTURES AND METHODS OF SYNTHESIS OF PIMS POLYMERS
    Publication number: 20190153154
    Abstract: A method of increasing the rigidity of PIM homo- or co-polymers including repeating units containing at least one biscatechol monomer having a fused spiro-bisindane (SBI) ring system of Formula (I), the SBI ring system including a bicyclic spiro-carbon: (I) wherein each R1 can be the same or different, each R2 can be the same or different and wherein R1 and/or R2 are selected from any one or more of H; straight or branched, saturated or unsaturated lower C1-C6 alkyl groups, wherein the lower alkyl groups can include aromatic or non-aromatic ring structures; R3OR4, R3O(C?O)R4, R3C(?O)OR4, or R3OH, wherein each of R3 and R4 are the same or different and are selected from straight or branched, saturated or unsaturated lower C1-C6 alkyl groups; and R5 and R represent suitable linking monomers, wherein the linking monomers can be the same or different and are preferably selected from any one or more tetrahalo aromatic monomers; and wherein the method includes the step of introducing an intra-molecular lock between

  • Directly photodefinable polymer compositions and methods thereof
    Patent number: 8053515
    Abstract: A polymer includes a first type of repeat unit represented by Formula I: where X is selected from —CH2—, —CH2—CH2—, or —O—; m is an integer from 0 to about 5; and where for the first type of repeat unit one of R1, R2, R3, and R4 is one of a maleimide containing group and for the second type of repeat unit one of R1, R2, R3, and R4 is a hindered aromatic group, a C8 or greater alkyl group, a C4 or greater halohydrocarbyl or perhalocarbyl group, a C7 or greater aralkyl group, or a heteroatom hydrocarbyl or halohydrocarbyl group.
