Abstract
Official abstract text for this publication.
The present invention is to provide a polymer which has a C—P bond. The present invention can provide a phosphoric acid-modified polymer having a double bond, and a phosphorus substituent containing a phosphorus atom that directly bonds to a carbon atom.
First claim
Opening claim text (preview).
The invention claimed is: 1. A modified polymer comprising: a phosphorus substituent containing a phosphorus atom that directly bonds to a carbon atom; and a double bond, wherein the phosphorus substituent is represented by Formula (1): wherein, R 1 and R 2 represent, the same or different, an alkyl group having from 10 to 30 carbons, that may have a substituent; and the phosphorus atom bonds to the carbon atom at a position indicated by *. 2. The modified polymer according to claim 1 , wherein the double bond is located at at least one of a main chain, a side chain, or a terminal. 3. The modified polymer according claim 1 , wherein a backbone of the phosphoric acid-modified polymer is a diene rubber. 4. The modified polymer according to claim 3 , wherein the diene rubber is at least one type selected from the group consisting of polyisoprene, polybutadiene, aromatic vinyl-conjugated diene copolymer rubber, butyl rubber, ethylene propylene diene rubber, and natural rubber. 5. The modified polymer according to claim 1 , wherein the carbon atom is located at at least one of a main chain, a side chain, or a terminal. 6. The modified polymer according to claim 1 , wherein the carbon atom forms a saturated bond.
