The invention relates to a novel low profile additive (LPA) for uncured polyester resins and the resultant molding compositions. The low profile additive is the reaction product of an ethylene/alphaolefin copolymer with a carboxylic acid or anhydride, to thereby form a non-thermoplastic carboxyl modified polyolefin. The novel LPA is a remarkably effective dimensional stabilizer and has displayed the ability to achieve net expansion in a cured polyester resin molding composition.

Carboxyl modified olefinic copolymer compositions

Amorphous moisture-curable, silane-substituted polymers having a saturated carbon backbone and a viscosity average molecular weight of between about 500 and about 20,000 provide desirable protection for weatherable substrates upon curing. Also disclosed are coating compositions containing such silane-substituted polymers; a method of protecting weatherable substrates employing such compositions; and composites produced by the method disclosed herein.
