The present invention provides methods of making low energy polymerizable monomers and resins for use in making dielectric materials. The methods comprise deprotecting or deacylating an organic alkali cleavable protecting group containing addition polymerizable, amine containing aromatic monomer or oligoaromatic phenol resin containing an organic alkali cleavable protecting group, such as a C2 to C9 alkanoyl group, preferably, an acyl group, by hydrolyzing to remove the protecting group in organic alkali in a polar solvent containing an excess of alkali C1 to C7 alkoxide and form a hydroxyl functional monomer or resin, followed by; reacting via nucleophilic substitution the resulting hydroxyl functional monomer or resin with an alpha-halide (a-halide) or strong acid conjugate leaving group containing arylcyclobutene compound in a polar solvent, to yield a product an arylcyclobutene-containing addition polymerizable or amine containing aromatic monomer or oligoaromatic phenol resin having an ether linkage from the cyclobutene ring to an aromatic group of the addition polymerizable aromatic monomer, aromatic amine or oligoaromatic phenol.
本发明提供了用于制造介电材料的低能可聚合单体和树脂的制造方法。这些方法包括通过在含有过量碱 C1 至 C7 烷氧基的极性溶剂中,在有机碱中水解去除保护基团,形成羟基官能团单体或树脂,从而对含有可加成聚合的、含胺的芳香族单体或低芳香族酚树脂进行脱保护或脱乙酰化;在极性溶剂中,通过亲核取代作用,使得到的羟基官能团单体或树脂与含有芳基环丁烯化合物的α-卤化物(a-卤化物)或强酸共轭离去基团反应,得到一种含有芳基环丁烯的可加成聚合或含胺的芳香族单体或低芳香族酚树脂,该产品具有从环丁烯环到可加成聚合芳香族单体、芳香族胺或低芳香族酚的芳香族基团的醚键。
