    • A vinyl copolymer is provided comprising a silanol group-containing (meth)acryl siloxane unit of formula (1): ##STR1## wherein R.sup.1 is hydrogen or methyl, R.sup.2, R.sup.3, and R.sup.4 are independently a monovalent C.sub.1 -C.sub.8 hydrocarbon group or a siloxy group, R.sup.5 is a monovalent C.sub.1 -C.sub.8 hydrocarbon group, n=1 to 12, and a=0 or 1. The vinyl copolymer is prepared by copolymerizing a polymerizable vinyl monomer with a silanol group-containing (meth)acryl siloxane in the presence of a radical initiator or by emulsion polymerizing a polymerizable vinyl monomer with a silanol group-containing (meth)acryl siloxane in an aqueous medium in the presence of a surfactant and a polymerization initiator. The copolymer is blended with a condensation catalyst to form a room temperature curable resin composition which crosslinks in the presence of moisture into a cured coating having weatherability, flexibility, and adherence.
