          abstract = {Viscoelastic rate-type fluid models involving the stress and its
observer-invariant time derivatives of higher order are used to
describe the behaviour of materials with complex microstructure, for example geomaterials
like asphalt, biomaterials such as vitreous in the eye, synthetic rubbers such as SBR (styrene butadiene rubber).
A standard model that belongs to the category of viscoelastic rate-type
fluid models of the second order is the model due to Burgers, which can be
viewed as a mixture of two Oldroyd--B models of the first order. This
viewpoint allows one to develop the whole hierarchy of generalized models
of a Burgers type. We study one such generalization.\!\! Carrying on the study
by Masmoudi \!\cite{Mas}, where he made a sketch of the proof of weak sequential stability of (hypothetical)
weak solutions to the so called Giesekus model, we prove long time and large data
existence of weak solutions to a Burgers-type model that can be written as a mixture of two Giesekus models in two
spatial dimensions.},
