Claim 2
Dependent Claim
36 words
A composition comprising a vicinal acryloxy hydroxyl derivative of linseed oil and an amount sufficient to stabilize said composition against viscosity increases of an N-alkylmorpholine, wherein the alkyl unit contains from 1 to 4 carbon atoms.
Claim 3
Dependent Claim
36 words
A composition as claimed in claim 1, wherein the amount of N-alkylmorpholine present is from 0.2 to 1.6 moles per mole of residual acrylic and methacrylic acid present in the acryloxy hydroxyl derivative of linseed oil.
