Abstract
Abstract Novel polymerisable compounds which can be used to form coatings on substrates such as glass fibres, having a substituent of the formula CH2=@-CO-NH-CO-O- wherein R is H or C1-5 alkyl, can be derived from the corresponding compound having an OH group instead of the said substituent.
