摘要： PURPOSE:To provide a polydiacetylene having such display functions as electroconductivity, electrochronism etc. along with high processability, constituted by such structure that polymeric side chain carrying both hydrogen bond-forming part and charge-transfer complex one is connected to the polymeric main chain through a spacer. CONSTITUTION:The objective polyacetylene having recurring unit of formula I or II[R is -A-X-B-Y; A is spacer represented by -(CH2)p- or -CH2O(CH2)q-, (p and q are each 1-10); B is spacer selected from -(CH2)a-COO-, -(CH2)b-O-, -(CH2)c-O- CH2-, and -(CH2)d-OCO- (a-d are each 1-5); X is hydrogen bond-forming part selected from -NHCOO-, -NHCO-, etc.; Y is charge-transfer complex part]. The synthesis of the charge-transfer complex part can be accomplished by conversion into complex with either a combination of polymeric side chain terminal group as donor and guest component as acceptor or its opposite one; however, the former being preferable. The polymeric side chain terminal group is to be of a compound having basic skeleton with either donor or acceptor nature, also carrying functional group, e.g. carboxyl one.

摘要： PURPOSE:Acidic or activated clay is calcined to give a high active catalyst and diisobutylene is subjected to catalytic dimerization using the catalyst to produce tetraisobutylene in high selectivity and yield. CONSTITUTION:Acidic or activated clay or silica-alumina is calcined. Then, the dimerization of diisobutylene is conducted in the presence of the resultant catalyst at 40-150 deg.C under normal pressure for 0.2-20hr to produce tetraisobutylene selectively. The acidic or activated clay is calcined at 400-600 deg.C and silica- alumina is at 450-850 deg.C in air for 3-8hr. The amount of the catalyst used in the reaction is 1-10wt% based on diisobutylene, when the reaction is carried out batchwise. Diisobutylene, as the starting material, is preferably free from trimer or other impurities and the water content is required to be less than 0.001wt%.
