Polymer Capsule and Process For the Preparation Thereof

A polymer capsule having a diameter of 10 to 1,000 nm which is prepared by copolymerization of a cucurbituril derivative represented by Formula 1 below with an organic compound represented by Formula 2 below:

• wherein,
• at least one or all of n A1's and n A2's is selected from the group consisting of a hydroxy group, a methyloxy group, a butyloxy group, a dodecabutyloxy group, a propynyloxy group, a hydroxyethyloxy group, a C1-C30 alkyloxycarbonyloxy group, a C1-C30 alkylcarbonyloxy group, a C1-C30 aminoalkyloxy group, —OC(═O)CH3, —OCH2CH2CH2SCH2COOH, —OCH2CH2CH2SCH2CH2NH2, and —OC(═O)CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH3, or is —O-A-CH═CH2 where A is C1-C20 alkylene in which oxygen, sulfur, or nitrogen may be inserted into a carbon-carbon bond of the alkylene;
• X is O, S, or NH;
• and
• n is an integer of 4 to 20, and
• (HS)j-Z-(SH)k, (2)
• wherein,
• Z is C1-C20 alkylene which may be substituted by one selected from the group consisting of HSCH2CH2CH2CH2CH2CH2SH, HSCH2CH2OCH2CH2OCH2CH2SH, HSCH2CH2(OH)CH2(OH)CH2SH, CH3CH2C(CH2OOCCH2CH2SH)3, and C(CH2OOCCH2CH2SH)4, and in which oxygen, sulfur, or nitrogen may be inserted into a carbon-carbon bond of the alkylene;
• and
• j and k are each independently an integer of 1 to 3.
