摘要:
The present invention relates to polymerizable cyclic urea derivatives which can be thermally split to give rise to an isocyanate group; and to a polymer having cyclic urea pendant groups, which can be cured by heating without any additional curing agent such as an isocyanate blocked with a volatile lower molecular weight material, so that any volatile material is not released at thermal curing process.
摘要:
A reactive acrylic resin micro-particle comprising a particulate body resin and a number of linear segments attached to said body resin and extending outwardly therefrom, said particulate body resin being composed of an internally gellated acrylic resin and having a mean grain diameter of 0.01 to 20 µ and said linear segments each being composed of a linear carbon chain of 1 to 100 carbon atoms, which may be interrupted by an oxygen, sulfur or nitrogen atom, which is connected at one end to said particulate body resin through a urethane, acyl urethane, urea or acyl urea bond and possessed of at the other end an ethylenically unsaturated bond. The invention also includes the preparation of said microparticles and a curable acrylic composition containing said microparticies, at least one polymerizable monomer or oligomer and a polymerization initiator.

A polymer comprising a carbon-carbon backbone chain and at least one N-(substituted oxalyl)carbamoyl group of the formula: -CO-NH-CO-CO-OR wherein R is a hydrocarbon group as a side chain attached to said backbone chain.
摘要:
A functional polymer whose molecules have a main chain of carbon-carbon bonds and one or more pendant functional groups each appended to the main chain via a carbonyliminocarbonyl linkage, in which the or each functional group is chosen from fluorinated, aminotriazine, photosensitive, bicyclic and spiro structure-containing groups, and in which the content of the functional groups plus the carbonyliminocarbonyl linkages per molecule is from 0.1 to 99.9% by weight.
摘要:
Novel polymerisable compounds which can be used to form coatings on substrates such as glass fibres, having a substituent of the formula wherein R is H or C 1-5 alkyl, can be derived from the corresponding compound having an OH group instead of the said substituent.
