Polymers are described that are prepared from di and mono-functional silicone and silane monomers of Formula 1 in which Y represents a direct bond or a oxy group; Rrepresents an optionally substituted organo group with at least one double bond which optionally may be an activated unsaturated moiety such as a (meth)acrylate group: for example 1-n-propoxy(acrylate) or ethenyl; and Rand Reach separately, and independently within each optional repeat unit, represent an optionally substituted hydrocarbo, hydrocarbo(oxy), hydrosilico and/or hydrosilico(oxy) groups; or example, methyl; or trimethylsiloxy; Rindependently represents an optionally substituted organo group with at least one double bond (such as Rabove) an optionally substituted hydrocarbo, and/or hydrosilico group for example trimethylsilyl or ethenyl; and n is from about 0 to about 2000; preferably from about 1 to about 100, for example n is 1. Such polymer precursors can be used to prepare flow modifying agents, defoamers and/or pressure sensitive adhesives. 

Polymer compositions

A composition of matter resistant to foaming comprising a hydrocarbon oil and an acrylate copolymer dispersed in the said hydrocarbon oil, which acrylated copolymer contains at last one polymerised fluorinated (meth)acrylate monomer wherein not more than three neighbouring carbon atoms in the said fluorinated (meth)acrylate monomer carry one or more fluorine substituents.
