Abstract
A homopolymer having a monomer unit such as an isopropylidene diallylmalonate unit; a process for producing said homopolymer comprising the step of homopolymerising a monomer such as isopropylidene diallylmalonate; a copolymer containing said monomer unit and an ethylene unit and/or α-olefin unit; and a process for producing said copolymer comprising the step of copolymerizing a monomer such as isopropylidene diallylmalonate with at least ethylene and/or an α-olefin.
Claims10
A homopolymer having a repeating unit represented by the following formula (2):
- wherein X1, X2, X3 and X4 are independently of one another an atom belonging to group 16 of the periodic table;
- R1 and R2 are independently of each other a hydrogen atom or a hydrocarbyl group having 1 to 20 carbon atoms, and R1 and R2 may be linked with each other;
- and A1, A2, A3, A4, A5, A6, A7, A8, A9 and A10 are independently of one another a hydrogen atom, a halogen atom, an alkyl group, an aralkyl group, an aryl group, a substituent-having silyl group, an alkoxy group, an aralkyloxy group, an aryloxy group, a disubstituent-having amino group, or a hydrocarbylthio group.
