Modifying Polymeric Materials By Amines

摘要

This invention relates to the modification of polymeric materials containing reactive carbon-to-carbon unsaturation and to amines, including piperazines, which are used in such modification. A polymeric material containing carbon-to-carbon bonds can be modified by crosslinking or to make it susceptible to crosslinking.

主权项

1. A process for modifying a polymeric material containing reactive carbon-to-carbon unsaturation, characterised in that the polymeric material is treated with a compound (I) containing in its molecule at least two moieties of the formulawherein X represents a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms; Y represents hydrogen or a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms; R′ represents hydrogen or a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms; Z represents oxygen or sulphur; and R represents a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms, at least one of the groups X and R being a multivalent substituted hydrocarbyl group linking two or moremoieties.
