The preparation of composites using epoxy-functional silicones as additives to phenolic resole resins.

Epoxy-functional polysiloxane modified phenolic resin compositions and composites

A lactone chain-extended polyester polyol of the present invention comprises the reaction product of a lactone and a previously chain-extended phenolic-based hydroxyl compound. The previously chain-extended phenolic-based hydroxyl compound may comprise the reaction product of (i) a lactone or an alkoxylating agent selected from the group consisting of alkylene oxides and alkylene carbonates, and (ii) a phenolic aralkylation polymer comprising the reaction product of a phenolic monomer having at least two free reactive positions; a styrene derivative; and a coupling agent. The previously chain-extended phenolic-based hydroxyl compound also may be chain-extended by reacting with a lactam to produce a lactam chain-extended polyester polyamide. The polyols and polyamides of the present invention provide unique combinations of hard and soft functionalities, which translates into materials exhibiting a unique combination of toughness and hardness. These materials are especially suitable for use in high solids coatings and in the development of resins which can be readily processed into thermoset resins. The materials also may function as compatibilizers for thermoplastics.

Lactone chain-extended phenolic polyester polyols

The present invention is directed to a method for preparing phenol aralkylation polymers by reaction among a phenolic monomer, a styrenic monomer and an aryl diolefin, characterized by the absence of a solvent, wherein a phenolic monomer is initially aralkylated in the presence of an acid catalyst with a first portion of at least one styrenic monomer to obtain an aralkylated phenol, the aralkylated phenol is reacted with an aryl diolefin to obtain a phenol aralkylation polymer, and then optionally, (though preferably) the phenol aralkylation polymer is further aralkylated with a second portion of at least one styrenic monomer.
