Oxygen absorption characteristics of blends of fatty acids from seed oils of rubber watermelon, soyabean and linseed
Material type:
TextSubject(s): Summary: Oxygen-induced polymerisation of blends of fatty acids from rubber seed (RSA), watermelon seed (MSA) soyabean (SBA) and linseed (LSA) was done with a view to optimising the drying performance of the semidrying ones for development of alkyd resin paint binders. The results obtained showed two types of behaviour in oxygenic absorption: a linear response by LSA/RSA and SBA/RSA blends in which oxygen absorbed increased directly with the amount of the more drying fatty acid; and a synergistic response by MSA/RSA, MSA/LSA blends in which oxygen absorption showed optimum values between 40-50 wt per cent of MSA. This behaviour by MSA holds good promise for development of alkyd resins.
