Epoxide-containing esters

Introduced: January 2025

Full Title

Full titles differ between systems:

IPC:

Compositions of homopolymers or copolymers of unsaturated aliphatic hydrocarbons having only one carbon-to-carbon double bond; Compositions of derivatives of such polymers > not modified by chemical after-treatment > Homopolymers or copolymers of ethene > Copolymers of ethene > with unsaturated hydrocarbons containing atoms other than carbon or hydrogen > with unsaturated acids, e.g. [meth]acrylic acid; with unsaturated esters, e.g. [meth]acrylic acid esters > Epoxide-containing esters

CPC:

Compositions of homopolymers or copolymers of unsaturated aliphatic hydrocarbons having only one carbon-to-carbon double bond; Compositions of derivatives of such polymers > not modified by chemical after-treatment > Homopolymers or copolymers of ethene > Copolymers of ethene (C08L23/16 takes precedence) > with unsaturated hydrocarbons containing atoms other than carbon or hydrogen > with unsaturated acids, e.g. [meth]acrylic acid; with unsaturated esters, e.g. [meth]acrylic acid esters > Epoxide-containing esters

No child classifications to compare. This is a leaf node in both IPC and CPC.
